A 1.00 L buffer solution is 0.200 mol L-1 in C6H5COOH and 0.250 mol L-1 in C6H5COOLİ. The Ka for C6H5COOH is 6.3 x 1o-5. a) What is the initial pH of the solution. b) What are the concentrations of the acid and the salt after the addition 50.0 mL of 1.00 mol L- HCI. c) Calculate the pH of the solution after the addition of HCI.
