NITRATION OF METHYL BENZOATE Purpose: The main objective of this experiment was to synthesize methyl nitrobenzoate from methyl benzoate‚ using the mixture of nitric and sulfuric acid by performing the process of electrophillic aromatic substitution. During this reaction‚ the combination of HNO3 and H2SO4 made a nitrating solution. The crystallization was done to accomplish pure product. The melting point and Thin Layer Chromatography (TLC) were performed to test the purity of the product. Using

The Effects of Fast Food on Health There are so many restaurants around the world today that could severely harm your health. Fast food has so many bad side effects such as: obesity‚ high cholesterol levels‚ and food poisoning. You could say that there are way more bad side effects than good side effects from obtaining fast food. Obesity has been ranked the number one health threat to Americans and causes up to 400‚000 deaths a year. In fast foods‚ the levels of Trans fat and calories are very

can reach a new pH level by interacting with soil. If water has a pH that is too high or too low‚ it can be life threatening to aquatic species and can corrode metal structures. After finding this out‚ I decided to test if water could reach an extreme pH just by interacting with soil around it. The question for this experiment therefore became the following. Will interaction with soil change the pH of water? I hypothesized that if water interacts with soil for three days‚ then the pH of the water will

Determination of pH Almira‚ Faerie Carleen Lucile L. Gallardo‚ Charlotte O. Group #6‚ Chemistry 18.1‚ MHEG1‚ Ma’am Arlou Angeles September 23‚ 2013 I. Abstract The acidity of the four unknown solutions were determined with the use of colorimetry using McIlvaine’s buffer solutions varying in proportion of its constituents (disodium phosphate and citric acid). These buffer solutions were subjected to the addition of corresponding pH indicators and the variation of colors depending on its pH level was

SLII The effect of three different pH levels (4‚ 7‚ 10) on the rate of germination of spanish beans Research Question: What is the effect of three different pH levels (4‚ 7‚ 10) on the rate of germination of spanish beans? Independent Variable: The different pH levels in the water would be the independent variable in this lab. Three different pH levels were tested‚ 4‚ 7 and 10‚ both 4 and 10 were chosen because they are 3 pH levels away from 7 which would be the regular pH level of water
