There is inadequate research/information on molds and how they are affected by acids. There is not sufficient information on the elimination or prevention of molds on household and grocery items. To test possible solutions, the growth of mold will be examined using different acids to help keep the mold at a low quantity. Two different substances, one with a high acidity and one with a low acidity, will be used along with water as our “mold repellants”. At the conclusion of each trial, each acid’s ability to prevent mold growth will be documented. Conducting this experiment will benefit the scientific world because it researches a problem that has not been thoroughly solved. Perhaps a way to prevent mold from growing can be developed with further study. This experiment will serve as a beginning to what could possibly become a great discovery. The results of this experiment will be beneficial to scientists and could possibly serve as a baseline concept for mold prevention and influence further experimentation.
Every acid has a different strength. The power of each acid determines where it is ranked in terms of its acidity. Generally, acids with a higher acidity can disintegrate more matter than an acid with a lower acidity. In this experiment, the acid’s ability to stop mold growth will be tested. The more acidic a certain acid is, the more likely it is to have a destructive effect on objects and matter. This is why it is predicted that the stronger acid will keep the mold growth to a minimum. The weaker acid is predicted to prevent only some of the mold from growing. The control group, which will be treated with water, is not predicted to control any of the mold development.
Molds typically grow in damp, warm environments. They c...

In the pH homeostasis lab, 6 experiments were conducted. The hypotheses were: If base is added to water then the pH will increase; If acid is added to water then the pH will decrease; If base is added to homogenate, then the pH will increase; If acid is added to homogenate, then the pH will decrease; If acid or base is added to buffer, then the pH will remain the same. After the experiments were conducted, the graphs were somewhat similar to the hypotheses.
I decided to experiment with pHs within the range pH 2 to pH7, as I

According to the results shown, 2 M hydrochloric acid that was more concentrated had a faster rate of reaction than less concentrated 0.5 M hydrochloric acid. As could be seen from Figure 1: processed data, 2 M hydrochloric acid’s average water displacement of 9.1 cm was much larger than 0.5 M hydrochloric acid’s water displacement of 0.3 cm. Therefore, the trend of the reaction rate increasing as the concentration increased was shown. The hypothesis was supported by the evidence obtained from this experiment.

The topic of this paper is acid deposition, also known as acid Rain. Acid rain is precipitation, as rain, snow or sleet containing relatively high concentration of acid forming chemicals. As the pollutants from coal, smoke, chemical manufacturing, and smelting, that have been released into the atmosphere and combine with water vapor, the harmful deposition is created (http://dictionary.reference.com/browse/acid+rain). Acid rain affects many things greatly.

Mold remediation is not as simple as it may seem, and if you don't do it right, the mold will simply come back. Even a small amount of mold that is left behind will spread, and you will be back to where you started. And because you may have convinced yourself that the problem went away, you may be slow to notice that it has returned, so it may come back stronger than before. The following are three reasons why you should use a professional mold remediation service instead of attempting the work yourself.
What is Mold? Under what conditions does mold do best? What types of substances does mold grow the most and the fastest? Mold is a microscopic organism, a furry growth of fungi and grows on organic substances that are exposed to moisture for a period of time. But there are some that can grow in conditions that are dryer and cold. Mold can be found everywhere inside buildings, homes, and the outdoors.
The purpose of this project was to discover how the pH level affects corrosion rate. The hypothesis was if the pH level affects the corrosion rate, then the lower the pH level is quicker the corrosion rate would be. This will happen because liquids below the pH level of 7 possess stronger acidic attributes. The effect of pH level on corrosion rate was determined by depositing a copper penny in each of three plastic cups, and then three different liquids by their pH levels, were assigned to be displaced into each cup formulating a chemical reaction to be observed. The results collected during this investigation contradicted with the intended result, this experiment was conducted to determine corrosion rate; Dana Puti Vingear (pH level: 4.5) 4 2/3 days, Tropicana Orange Juice (pH level 3.88) 6 1/3 days, and Sprite (pH level: 3.4) 8 days. The results showed that the hypothesis was refuted. This happened because the preconceived idea was that the liquid with the lowest pH level; Sprite, would have the quickest corrosion rate. Dana Puti Vinegar had the quickest corrosion rate proving the statement wrong, it was discovered that it contains ethanoic acid; acid containing twice the amount of carbon dioxide than a regular acid. To further understand this topic, future research could include; how does the amount of liquid incorporated affect the corrosion rate, how does the temperature of the liquid affect the corrosion rate, and how does the purity of iron affect the corrosion rate?
From looking at the results I can conclude that when the pH was 3 and
Allergies are especially unique in the medical field because they differ among patients. An allergy is a specific immunologic reaction to a normally harmless substance, one that does not bother most people. People with allergies are often sensitive to many substances. Common allergens that cause allergic reactions include seasonal, outdoor allergens like tree, grass, and weed pollen, and year-round indoor allergens including dust particles, animal dander, and indoor mold. Most people usually can be cured by various treatments.
Also the investigation will be performed in a sensible manner and there is no dangerous behaviour. Prediction When the experiment is taking place I believe that the magnesium in the hydrochloric acid will begin to bubble and then disappear, I also
