Question
A buffer solution contains 0.387 M NaH,PO4 and 0.212 M K2HPO4. Determine the pH change when 0.061 mol HCIO, is added to 1.00 L of the buffer. pH change =| A buffer solution contains 0.229 M CGH;NH3CI and 0.381 M C,H3NH2 (aniline). Determine the pH change when 0.077 mol HCl is added to 1.00 L of the buffer. pH after addition – pH before addition = pH change =| A buffer solution is 0.301 M in HCN and 0.274 M in KCN . If K, for HCN is 4.0×10-10 , what is the pH of this buffer solution?
