answer an it was incorrect.
A buffer solution that is 0.301 M in CH, COOH and 0.301 M in CH3COONa has a pH of 4.74. The addition of 0.01 mol of H, 0 to 1.0 L of this buffer would cause the pH to not change The capacity of this buffer for added H30+ could be increased by the addition of 0.112 mol of the salt A...
