    Abstract Water “hardness” was analyzed in this experiment‚ through the determination of CaCO3 concentration. This was achieved by the titration of an unknown solution using a standardized 0.1M EDTA‚ and addition of Eriochrome Black T to the unknown‚ to indicate the endpoint of the titration. The average concentration of CaCO3 obtained was 1034 ppm‚ with a standard deviation of 2.4495. The results indicate that the unknown solution can be considered as hard water. Introduction The

    In the first reaction‚ magnesium was burned to produce magnesium oxide. The reaction produced a bright light‚ which is evidence of a chemical change. The second reaction occurred as a result of solid magnesium reacting with hydrochloric acid. The reaction produced heat and bubbles‚ both indications of a chemical change. A wood splint was used to determine that the gas produced was hydrogen gas‚ hence the other product is magnesium dichloride. In the third reaction‚ ammonium carbonate was heated to

    sensory effect of esters. Isopentyl acetate is made from the direct esterification of acetic acid and isopentyl alcohol. The direct esterification of acetic acid and isopentyl alcohol is an equilibrium reaction that shifts the product to the side by using the excess of one of the starting reagents. Acetic acid usually used in excess because it is easier to remove from the reaction. The excess acetic acid and the remaining isopentyl alcohol are removed through extraction with water and sodium bicarbonate

    EXP-10 CHEM 233L SYNTHESIS OF p-BROMOANILINE Introduction: In this experiment‚ p-bromoaniline was synthesized in three steps starting from aniline. Since the amino group of aniline is a strong activator of aromatic ring‚ direct bromination is impractical (equation 1). In order to make a desired product‚ amino group needed to be protected as the acetamide which also maintained ortho and para position but slowed down the rate of reaction (equation 2). Slow reaction rate would increase
