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... ... middle of paper ... ...Health Topics.

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

Mold is something that we often take for granted, as something that makes us have to throw the bread away or the cheese smell bad.
Ensure gloves are worn at all times when handling strong acids and bases within the experiment of the preparation of benzocaine. 4-aminobenzoic acid (3.0g, 0.022 moles) was suspended into a dry round-bottomed flask (100cm3) followed by methylated sprits (20 cm3). Taking extra care the concentrated sulphuric acid of (3.0 cm3, 0.031 moles) was added. Immediately after the condenser was fitted on, and the components in the flask were swirled gently to mix components. It should be ensured that the reactants of the concentrated sulphuric acid and the 4-aminobenzoic acid were not clustered in the ground glass joint between the condenser itself and the flask. In order to heat the mixture to a boiling point, a heating mantle was used and then further left for gently refluxing for a constituent time of forty minutes. After the duration of the consistent forty minutes the rou...

If your home has experienced a flood, leak, or some type of water damage, there is a good chance that it has mold growing somewhere. Even if you can’t see it, and the water damage has been repaired, mold can still be present. After flooding or water damage happens, you should call a professional to come and test for mold as soon as possible.
From looking at the results I can conclude that when the pH was 3 and

Mold growth in your commercial building can cause health concerns and compromise your building’s integrity. Because mold grows quickly in damp conditions and thrives on wood, insulation, carpet, paper, and other organic surfaces where moisture and oxygen are present, it’s an especially big problem during the spring season. Prevent health concerns like asthma, respiratory infections, breathing difficulties, itchy eyes, nasal congestion, and skin irritations when you reduce mold in several ways.
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?
In conclusion people can now see that everything that was said all ties together in science, and can be used in science. Acids, bases, triple beam balances, sour and fruit flavored candy, ph levels, balloons, sodium bicarbonate, test tubes and racks, and of course acid-base reactions. This research paper tells people very much on all of those things, and should have made an impact on someone’s knowledge on the subjects.
