I'm really stuck on these questions, can anyone show me how to do them?
A buffer solution is prepared by mixing 71.0 ml of 0.0361 M sodium hydrogen sulfite with 81.2 ml of 0.0297 M sodium sulfite. A table of pKa values can be found here. Calculate the pH (to two decimal places) of this solution. Assume the 5% approximation is valid and that the volumes are additive. Calculate the pH (to two decimal places) of the buffer solution after the addition of 366 ml of a 0.00113 M solution of barium hydroxide to the existing buffer solution. Assume the 5% approximation is valid and that the volumes are additive.
