How Bleach Works Bleach is an amazing thing. It gets tough spots off your white clothes in a jiffy and makes it look brand new. A lot of people use this product, but no one has the time to actually figure out how it works. The element that is inside bleach includes Chlorine. “A Swedish pharmacist named Carl Wilhem Scheele released a few drops of hydrochloric acid onto a piece of manganese dioxide. Within seconds a greenish - yellow gas arose. The greenish-yellow gas was actually an element which was only recognized several decades later by English Chemist Sir Humphery Davy” (american chem). Suprisingly the word chlorine comes from the Greek Word Khloros which means greenish-yelllow. Many people think that bleach is only used to whiten and brighten clothes. Although that is not necessarily true. Scientists have now learned to use bleach in many different ways. They use it to eliminate germs, sterilize equipment, and it even makes our water cleaner. A plus side of using chlorine is that it is an abundant and desirable element which make it a great product for use. Chlorine is one of the essential “building blocks of our planet.”

The bleach that we use to clean drinking water is the same bleach that is used to clean a pool. The only difference is that the amount used to clean water is different from a pool. The amount of bleach in a pool is 3ppm ppm stands for part per million. There is 2ppm to 3ppm of bleach in our drinking water depending on the contaamination. Although not a lot of people agree with cleaning our drinking water with Chlorine which is in bleach. Although howstuffworks.com says “It is a whole lot safer to drink chlorinated water than conatminated water with disease causing
Our product is a package of 25 tiny tablets made of chlorine, which purifies unsanitary water. This results in fresh and clean water in a matter of minutes! Since our release in 2013, sales have been increasing in the Canadian market. Our product, “Purifers” is sold in every sporting goods store across Canada (Sport Chek, Canadian Tire, etc...).
The purpose of this experiment was to examine how the stoichiometry, “the quantitative relationships between substances involved in a chemical reaction”, can be applied to determine the quantity of sodium hypochlorite found in a bleach product. This experiment allowed it to determine how much oxidizing agent is in a cleaner by using a redox reaction, which is a reaction involving the transfer of electrons from the compound being oxidized to the compound being reduced. To determine the amount of oxidizing agent, it is necessary to accurately measure out known amounts of redox reactants, know the stoichiometry
It’s no mystery that having clean water is a fundamental element to living in a prosperous society and one of the few things essential for human survival. Water not only sustains our health, but is required in making everything from electronics to clothes. Clean water may seem as ordinary as putting on your shoes, but it’s a daily party of our life that’s being threatened.
Green washing: The disinformation disseminated by an organization so as to present an environmentally responsible public image. In order for big companies to stay on top of the market today, they are forced to think of advertising strategies to help their public image and advertise their product. Over the years the system has become very complex and also very questionable. Companies are willing to lie, change their logo, and sometimes even their company name just to keep their name and image clean in front of the public just to make sure that they are making their money. Green washing helps this by advertising to the public that they are environmentally supportive and responsible. Most people that are into buying “green products” do not even realize that the company they are buying from is green washing in some sort of way just so that they can attract attention to the public. Green washing companies may advertise that they are “eco-friendly”, but when it comes down to it, the facts hidden behind the curtains beg to differ. Just like in the green washing video we watched in class, the companies may look great compared to the worst companies, but that does not mean what they are doing is still productive for our environmental movement. One company that has been notorious for their green washing efforts for the past couple of decades is the Oil/energy company: British Petroleum a.k.a. Beyond Petroleum. They are one of the world’s largest leading oil companies who has also becoming a large energy supplying company with presence in petrochemicals, gas, and solar divisions. Over the past twenty years BP has been the cause of several deadly disasters in the oil business in the U.S. and around the world. Despite their green washing effor...
Detergent are defined as "a cleansing substance that acts similarly to soap but is made from chemical compounds rather than fats and lye" (The American Heritage Dictionary of the English Language). Modern detergents contain a chemical called a surfactant which can cause water and soil pollution and is quite harmful to plants. An average Australian house can produce about 400 litres of grey water a day. This water may not be used again. But with rising costs and people’s awareness of saving water, more and more people start to use their water resources more wisely. The Australian Government encourages citizens to use grey water for the garden, for example waste water from the bathroom, hand basin, shower, and laundry can be used to water the household plants. However, the statistic ( Table 1 and Table 2) shows that the de...
Dofasco uses hydrochloric acid to remove scale, oxides and other impurities that form on the surface of hot-rolled steel coils in a finishing process-a pickling line. Hot-rolled iron moves through baths of hydrochloric acid to remove impurities that form on the surface of the steel during the manufacturing process. The acid is used as a substance to create a clean-surfaced product. Hydrochloric acid is a clear, colorless, solution with a strong odour made of hydrogen chloride ions and water. This acid is highly corrosive and is used for many industrial purposes such as the pickling process. It is highly reactive, which is why it works efficiently to remove impurities off the surface of steel when it reacts with the steel. During the hot rolling of the
Detergent comes from the Latin word detergere meaning to clean, it is defined as a cleansing agent. Therefore, water itself is a detergent. This essay looks at soap and soapless (or synthetic) detergents. Both substances we use everyday and have a big market commercially, they effect everyone. Soaps are made from natural products and soapless detergents are produced chemically, each having advantages and disadvantages.
Excessive bleaching attempts can damage enamel, as can overly acidic products. You may end up with more porous enamel or a bluish tinge.
Laundry Detergents - Unscented products, biodegradable These are just some of the substitutes for harmful chemicals in the house. At least when you clean you house you don’t have to worry about hurting your child or yourself if you use the alternatives.

...process adds from 10 to 15 percent to the price of the fabric, industries still save money because more products can be made in less time. Therefore increasing profits, as well as, reflecting the savings onto the consumers. Other advantages of ‘biostoning’ include, enzymes can be recycled, reduced strain on the industrial washing machines, shorter treatment times, and imperfections are significantly reduced, hence increasing productivity and efficiency. Consequently, this saves the environment by reducing water consumption and waste pollution. The elimination of pumice powder and dust creates a less intensive and safer working condition. However, one problem with biostoning was "back staining" this occurs when loosened dye particles redeposit onto the surface of the fabric, causing discoloration. Such setback can be immensely reduced by optimizing running conditions.
Laundry detergents have ingredients which consist of calcium and magnesium in washing solutions which provide its advantage to eradicate dirt or stains from our clothes with more efficiency than just normal water. Although laundry detergents can help remove dirt, stains, or germs like bacteria on our clothes, they may contain strong and dangerous chemicals. Laundry detergents can be a risk if swallowed, and cause nausea, vomiting, convulsions, irritated skin and eye, or even comas. In addition, you must keep these substance away from your child since they might not know what it is and might try
When corals bleach they not only put themselves in danger as they become highly breakable, countless species relying on the coral reef for safekeeping no longer have a durable dwelling area once the algae is gone (Marshall, & Schuttenberg, 2006). Additionally, humans are also negatively impacted by coral bleaching because the substantial amount of economic benefits that they provide:
Our drinking water is protected by the Environmental Protection Agency’s’ Safe Drinking Water Act (SDWA). Underneath the SDWA the Environmental Protection Agency (EPA) “sets standards for drinking water quality” and the “technical and financial programs” to ensure the safety (Environmental Protection Agency, 2017). One standard that the EPA regulates is the contaminants and their limits, that are authorized to be in our drinking water. To provide these standards underneath the contaminant regulation is to create cost analysis and health risk reductions (Environmental Protection Agency, 2016). A “contaminant” is “any physical, chemical, biological, or radiological substance or matter in water” (Environmental Protection Agency, 2017).
Cyanuric Acid - Protects chlorine from sunlight and determines the required Free Chlorine level. Cyanuric acid, often called stabilizer or conditioner, both protects Free Chlorine from sunlight and lowers its effective strength. The higher the Cyanuric Acid level, the more Free Chlorine you need to use to get the same effect. It is important to know your Cyanuric Acid level so you can figure out what Free Chlorine level to aim for.
Water plays such an important role in our daily lives. 70% of our body is composed of water. 70% of the earth surface is also made up of water, but out of the 70%, only 1/3 of water is consumable. In fact, this amount has been continuously to decrease as more and more industries began to pollute and damage the water. For example, many toxic chemicals may be released into the water thus making the water impure. Such pollutions and damages lead the water to be contaminated and inconsumable as it may cause severe diseases. Water purification can remove all the unnecessary bacteria and viruses from the water that is hazardous for our health. Water purification may also improve the flavor and appearance of water. It removes the unpleasant odor. Therefore, water purification became one of the most useful and popular process used by people all over the world today. It is by far the most recommended and safest water treatment that is commonly used to purify damaged water into consumable water. Water purification provides us with safe, pure and clean water to consume and use.
