Consider a solution of 2.0 M HCN and 1.0 M NaCN (Ka for HCN = 6.2 × 10–10). Which of the following statements is true?


▸ The solution is not a buffer because [HCN] is not equal to [CN–].

▸ The pH will be below 7.00 because the concentration of the acid is greater than that of the base.

▸ [OH–] > [H+]

▸ The buffer will be more resistant to pH changes from addition of strong acid than of strong base.

▸ All of these are false.
