- Use Table 13-3 to help answer the following questions. a. Which is the stronger base, ClO4 or C6H5NH2? b. Which is the stronger base, H2O or C6H5NH2? c. Which is the stronger base, OH or C6H5NH2? d. Which is the stronger base, C6H5NH2 or CH3NH2?arrow_forwardA solution contains a mixture of acids: 0.50 M HA (Ka = 1 103), 0.20 M HB (Ka = 1.0 1010), and 0.10 M HC (Ka = 1.0 1012). Calculate the [H] in this solution.arrow_forwardAscorbic acid (vitamin C, C6H8O6) is a diprotic acid (Ka1 = 6.8 105 and Ka2 = 2.7 1012). What is the pH of a solution that contains 5.0 mg of acid per millilitre of solution? Ascorbic acidarrow_forward
