A student needs to make a buffer solution, so he prepares a 0.200 M solution of benzoic acid, C6H5COOH Ka=6.46x10-5 and a 0.200 M solution of its salt sodium benzoate, NaC6H5COO. To check that he prepared the solutions correctly, he measures their pH. Calculate the expected pH for each solution. C6H5COOH H*+ C6H5CO0" and C6H5COO" + H2O 5 C6H5COOH + OH
