analyze the pH of a mixture of a strong base and weak acid. The purpose of the guided-inquiry lab was to analyze the concentration of sodium carbonate by titrating the substance using a nitic acid solution. Introductory Activity 5 mL of both 0.2 M ammonia and 0.1 M acetic acid were placed in separate test tubes and their pH was determined with pH paper. A mixture was created by pouring both together and its final pH was recorded. The strength of the acid and base was determined and whether the two had

exposed to acids and bases everyday. For example, citric acid is in lots of citrus foods such as lemons, oranges and grapefruits. It is also added to foods for flavouring, non perishable, and cleaning supply. Citric acid creates a taste that is sweet and sour.

“Acid/Base” lab’s purpose was to introduce extractions of one of the four neutral organic compounds (4-chlorobenzophene, biphenyl, trans-stilbene, and trans-chalcone). We then were asked to test the solubility of our selected neutral compound with hexane, water, methanol, and ethyl acetate to find the solvent that only dissolved the neutral compound while introduced to heat. Once the solvent was chosen, we purified the compound by recrystallization, and then concluded that my neutral organic compound

How does acid rain affect the growth of plants? Aim: to determine how simulated acid rain affects the growth of radishes. Hypothesis: As the solution that is used to water the plants becomes more acidic, the height of the plants will decrease. Therefore, it is expected that radishes watered with distilled water which has a pH of 7 will exhibit the best growth than those watered with acidic solutions. Variables Independent variable: the pH of the solution Dependent variable: the height of radishes

the inclusion of an organic acid, it protonates the MC to form MCH+. This compound itself has a different absorbance band relative to MC, which was found to be around 408 nm in acetone and 453 nm in cyclohexane. Because the reaction must follow this sequence MCH+→ MC → SP, the corresponding rate of decay must be slower. As shown in Table 1 and 2, the decay rate with the addition of TFA is significantly lower relative to just SP in the solution. However, increasing acid concentration slows down the

time. In a couple of my old posts, I mentioned that products with an extremely high pH can be problematic. I also spoke with many people on various sites, or through private emails and requests for help on how to clear up their acne. I mentioned the acid mantle barrier and why it is important, but beyond that I have tried to stay away from being too scholarly on this blog. Actually being surrounded by science and pH's 24/7 as a Laboratorian, I don't really get the greatest pleasure posting TL;DR dissertation

Introduction: Acid Rain, or more specifically, acid precipitation, is an environmental phenomena. It is composed of sulfuric acid and nitric acid, in addition to water, which come to be due to the interactions between the water and atmospheric pollutants, such as sulfur oxide and nitric oxide. This combination of strong acids in water is known to be detrimental to the environment, infrastructure, and the health of people. Due to the water cycle, other water bodies, such as lakes and streams, are

Folic Acid Biology Internal Folate acid is a B vitamin that is essential to humans and can be found in a large variety of foods including leafy vegetables, citrus fruits, wholemeal bread, yeast, and liver. Pteroylmonoglutamic acid or commonly known as folic acid is the man made version of folate. Folic acid is used in dietary supplements as it is easier to absorb into the body and is stable, compared to the naturally produced folate. Unlike natural folate, which is instantly absorbed by the mucosa

1. Acids are ionic compounds that release H+ when in contact with water. LABORATORY EXERCISE #3: Acids, Bases & pH What is the effect of acids and bases on biological solutions?* INTRODUCTION It is important for organisms to be able to protect themselves from changes in internal and environmental pH. Any changes could disrupt metabolic activities. Organisms have developed ways in which to cope with these changes. Today you will look at how some biological materials can help moderate drastic swings

Beginning with this phenomenons name, acid rain, it has always had an distinguishable pull of attraction towards me. Commencing from the first time I heard about it in the years of my elementary, I have always had a keen interest in this oddly named rain. One would think any type of rain is beneficial to all natural living forms, but with my discovery of acid rain it seems not. Along with my envisionment of what acid rain is, it has always been a grey area in my mind and thoughts. Is the rain green
