Chemistry

An enzymatic reaction takes place in a 10 ml solution that has atotal citrate (plus citric acid) concentration of 120 mM and aninitial pH of 7.00. During the reaction 0.2 millimoles of H+ areproduced. The relevant pKa of citric acid is 6.40. A) Calculate thefinal pH of the solution. B) What would the final pH of thesolution be if the citrate were absent from the solution and noother buffering agents were present (assuming a starting pH of 7.00again, basically, what would be the pH is you added the same amountof acid to that amount of water)?
