EXPERIMENT 7PROPERTIES OF ACIDS, BASES AND BUFFERSName:Dhara PatelDate:March 14, 2008Objective:To identify the compound given by using performing solubility test to distinguish if it is soluble in water, acid or basic solution. Then, categorizing the acid and the basic solution according to their acid-base character as pH indicator assist by showing unique color of pH level. Lastly, comparing how many amount of acid and basic solution is required to produce a major pH change in a given volume of buffer solution while comparing to distilled water. Discussion:In this lab, four representative solutions were given: benzoic acid, aniline, p-aminobenzoic acid and benzamide. Then, tested if these solutions are soluble in water, acid solution or basic solution by observation certain reaction such as precipitation or any kind of blending between the two solutions. Benzoic acid did not dissolve in water or in acid solution, but cleared up in sodium hydroxide solution.
