pH calculation questions - pH of a buffer solution Finally we have a set of equations qbq2.4 and qbq2.5. When solved they give n a =0.036 and n b =0.064. From qbq2.2 we get that we have to add 0.036 mole of HCl, or 36 mL of 1 M solution. We can use pH calculator to check the result. Create a solution ...
