For a solution equimolar in HCN and NaCN, which statement is false?
| A. | 
 [H+] is larger than it would be if only the HCN were in solution.  | 
|
| B. | 
 Addition of NaOH will increase [CN–] and decrease [HCN].  | 
|
| C. | 
 [H+] is equal to Ka.  | 
|
| D. | 
 This is an example of the common-ion effect.  | 
|
| E. | 
 Addition of more NaCN will shift the acid-dissociation equilibrium of HCN to the left.  | 
Answer is
[H+] is equal to Ka this statement is false
regarding common ion effect all other state ments are correct
Ka is the percentage of the dissociation of H+ which will depend on concentration of HCN whic was not equal to H+
