1. a. In the laboratory, a general chemistry student measured the pH of a 0.331 M aqueous solution of hypochlorous acid to be 3.986. Use the information she obtained to determine the Ka for this acid. b.In the laboratory, a general chemistry student measured the pH of a 0.331 M aqueous solution of acetylsalicylic acid (aspirin), HC9H7O4 to be 1.985. Use the information she obtained to determine the Ka for this acid.
Calculate the pH of a solution that is prepared by dissolving 0.500 mol of hydrocyanic acid (HCN, KA = 6.17x10-19) and 0.187 mol of acetylsalicylic acid (HC,H,04, K4 = 3.40x104) in water and diluting to 3.40 L. Also, calculate the equilibrium concentrations of HCN, CN, HC,H,O4, and C,H,O4. Do not make an approximation unless the initial acid concentration is greater than 1000 × K. (Hint: The pH will be determined by the stronger acid of this pair.) pH = [HCN]=...
