2. For a solution equimolar in HCN and NaCN, which statement is false? a. This is an example of the common ion effect. b. The [H+] is larger than it would be if only the HCN was in solution. c. The [H+] is equal to the Ka. d. Addition of more NaCN will shift the acid dissociation equilibrium of HCN to the left. e. Addition of NaOH will increase [CN–] and decrease [HCN]. please explain option B and C
