A) A 100 mL 0.15 M NaOH is added to 50 mL of 0.12 M HF acid. Calculate the pH of this solution. B) A 150 mL of 0.15 M NH3 is slowly added to 25 mL of 02 M HCl. What is the pH of the resulting solution?. Is this final solution buffered? I was able to solve A and got 12.78 as my pH. I mostly just want to check that one and figure out how to do B.
