0.2 mol of gaseous HCl is added to 1.0 L of a buffer solution that contains...

0.2 mol of gaseous HCl is added to 1.0 L of a buffer solution that contains 3.0 M CH3COOH and 3.0 M CH3COONa. What is the pH of the solution? Assume that Ka for CH3COOH is 10-5. Assume also that the volume of the solution does not change when the HCl is added. Type your answer in decimal number carrying only one digit after decimal. So you must round up or down at the second digit after decimal. For example,...
