forensic context of the remains. The use of undiluted household bleach, as a means of defleshing cadavers is notably controversial in the forensic science literature. Specifically, when bleach is introduced to forensically significant skeletal material, the potential for cortical exfoliation due to the corrosive nature of bleach (sodium hypochlorite) poses a significant threat to the integrity of the outer cortex of the bone. Bleach cleans and whitens bones, which may be appropriate for museum display;
Bleach can be used to remove color from another substance or clean the water that we, humans, drink everyday. Even though bleach is very helpful and commonly used in our environment, it is also very reactive and unstable if it is not used correctly. For my experiment, I will be making an electronic device that will function as a colorimeter. Using the colorimeter, I will measure the concentration of blue dye in sports drinks, and find the rate at which blue dye disappears when it is mixed with bleach
significant risk to the health of living organisms and to the environment. Are there any viable alternatives to chlorine bleach which could be more forgiving to the environment? Introduction (245 words) WHAT IS CHLORINE BLEACH Bleaches are used as household chemicals to whiten clothes, remove stains and to be used as disinfectants, often by oxidation (Mittal, 2007). Numerous types of bleach contain strong bactericidal properties, and are used for disinfecting and sterilizing, thus why chlorine-based bleaches
Bleach is a chemical that is typically used in the household. It can be used to remove stains, lighten hair, sterilize pools, and kill weeds in a garden. It typically either contains chlorine or a peroxide like hydrogen peroxide, depending on what it’s used for. Bleach is harmful when ingested, in contact with skin, or breathed in. It is very toxic if any of those things happen. When a small amount is swallowed, over 200 milliliters can cause diarrhea, an inflamed esophagus, and internal bleeding
liquid bleach that my mom said worked wonders. The toilet I cleaned using the Ajax the sink I cleaned using the Ajax there seemed to be no need for the other two. Then I saw it- the bath tub, AH! There was a ring around the bath tub that I knew would be difficult to clean off. I decided to add the ammonia I scrubbed at the ring but it was not coming off. I then looked around thinking what to do… "The Bleach!" I shouted aloud. And then -- it hit me, my mom's hand. "Never, Never, Never, use Bleach with
In 1986 Kurt, Krist, and Chad Channing (drums) started playing together for fun. At first they were called “Fecal Matter”, but Kurt decided the last and final name was; “Nirvana”. The first album they made under Nirvana was “Bleach”, in 1989. For a while, they just played and messed around keeping a few recordings around, but they decided they wanted to make a record. And Sub Pop Records in Seattle made one for them. The record was a major hit, It included songs such as; Blew
INTRODUCTION During restoration of an affected tooth, if any margins between the composite restoration and tooth of concern are open, micro-leakage can occur1. Micro-leakage is a phenomenon in dentistry resulting from imperfect bonding that allows the movement of bacteria and fluids between the restoration and tooth of interest2. When a composite restoration is placed and undergoes polymerization through curing, shrinkage occurs. Research has shown that the percent of gaps between composite restorations
2.4.1 Peroxide based Bleaching Agents These products usually contains hydrogen peroxide or one of its precursors as an oxidizing agent a. Hydrogen peroxide (HP,H2O2) is an effective bleaching agent. It is a pale blue liquid and is slightly more viscous than water. The molar mass of hydrogen peroxide is 34.0147g/mol .As the molecular weight of hydrogen peroxide is low it can penetrate dentin and break the bond of organic and inorganic compound inside the dentinal tubules[36] .The photolysis of hydrogen
Estimation of Chlorine in Household Bleach In this investigation, I am looking to determine the amount of chlorine present in household bleach. However, in order to do this I would have to calculate the mass represented by chlorine in the mass of the household bleach. After doing that, I would then have to represent this as a percentage. In order to calculate the mass represented by the chlorine in the mass of the household bleach, I would have to titrate this solution, along with an
Analysis of an Advertisement for Bleach by Domestos The product was advertised in OK! magazine on August 21st 2002 For my GCSE Media coursework, I have chosen to analyse an advertisement for Demestos bleach. Domestos has been protecting families in the UK for over 70 years - and originally came in brown glass bottles. The advert for Demestos I have chosen to analyse uses a young male model (Alex Sibley from Big Brother) struggling to get to the bleach. As if to win people over through
Chemistry ISU Rought Draft Household Cleaners What is it? Household cleaners are products such as Bleach that are created for the sole purpose of simplifying tasks that concern the maintenance of a home or building. There are many different types of cleaners, including but not limited to bleach, sanitizers and ammonia. Some cleaners can be used on almost any surface and are often used to kill bacteria. History Household cleaners, or chemical cleaners as an alternative name have been used for
COLOUR OF NATURAL HEALTHY TEETH Add a caption Teeth are composed of a surface enamel layer, which is whiter and semitransparent, and an underlying dentin layer, which is darker and less transparent. The colour of teeth varies among the gum, tip and central areas according to the thickness, reflectance of different colours and translucency in enamel and dentin. The colour of healthy teeth is primarily determined by the dentin and is modified by: 1. The colour of the enamel
and cleaning agent mixed such that the oil molecules cannot “clump together”. Hence, since bleach has no surfactants, it has no emulsifier to stabilise the emulsion created and there is no difference observed in the volume of oil before and after stirring. The bleach that I used is chlorine bleach, which contains sodium hypochlorite, its main ingredient. Bleach cleans by the process called oxidation. Bleach does not actually remove stains, it just makes them colourless. It breaks the chemical bonds
Methylene blue was the only true indicator as to whether glycolysis and respiration occurred. If dissolved oxygen levels were low then the methylene blue would become colorless and bleach. This was the case for four out of the seven test tubes. The results have shown that test tubes one, four, five, and seven did bleach. This is because the process of respiration had occurred in those tubes; therefore, the dissolved oxygen levels were low and bleaching was forced to occur. Test tube one bleached
My Science Fair experiment is based on four main products: ibuprofen, acetic acid, bleach, and bread. The name of this experiment is "Bread vs. Chemicals." The goal of this experiment is to determine which chemical bread can survive in the longest. I will conduct multiple trials of each type of chemical and promptly record the results. I will use three containers, one for each chemical, and place a piece of bread in each to observe how long the bread can survive without falling apart. This experiment
products that are meant for purposes where bleach as an ingredient would be harmful and would cause damage to the surface that the product is being used. Some examples of these types of products where bleach would be damaging would include laundry detergent, carpet cleaner, or oven cleaner. Clorox discovered that they were struggling to sell these kinds of items because people tend to associate the brand Clorox with bleach, regardless of whether the product has bleach in it or not. Since people associate
Starting with the basics is the composition of stain removers. One ingredient in stain removers is ammonia (NH3). When ammonia is in its alkaline state, it is very efficient in destroying bacteria and breaking down stains. The next component is bleach (NaClO), otherwise known as sodium hypochlorite which disinfects and whitens fabrics. “It works by oxidizing (or stealing electrons from) the compounds comprising germs and stains, which effectively breaks down their molecular bonds” (ehow.com).
eye or create long lasting, easily concealable light sources such as glow sticks. The goal of this experiment was to find the most appropriate solvent in which to dissolve luminol and examine the effects of adding reagents such as sodium hydroxide, bleach, and hydrogen peroxide to the solution, aiming to find the concentrations that caused the luminol to glow for the longest period of time. Although a rather complicated reaction, the luminol reacted best with a comparatively simple solution. Introduction
sanitizing solution is by using regular household bleach (5.25% Sodium Hypochlorite). In this respect, ensure that the bleach is not ultra-bleach or extra strength bleach. It is also worth noting that only pure bleach should be used without any additional additives, and it should never be mixed with detergent which will reduce the strength of the sanitizing solutions. The following table explains how to make various sanitizing solutions using household bleach (5.25% Sodium
if I were to dab the area where the permanent marker is with rubbing alcohol, then the rubbing alcohol will remove the ink better than the other solvents. This experiment was supposed to prove if vinegar, rubbing alcohol, nail polish remover, or bleach would have removed the stain better off the pieces of fabric. I used two types of permanent marker: Type A and Type B. I used two types of markers to see if different brands would have affected the removal of the ink. Different color dyes also
