Question

Which pair will show common Ion effect?

Answer 1

Answer:

NH4OH is weak base to which NH4Cl is added which provides common NH4+ion dissociation of NH4OH is suppressed.

Answer 2

ANSWER

Those ions will show common ion effect in which one or both them does not dissociate completely.

NaCl and HCl dissociate completely as one of them is acid and other is salt of strong acid and strong base.

AgCN and KCN dissociate completely as one of them is acid and other is salt of strong acid and strong base.

NH4OH is weak base to which NH4Cl is added which provides common NH

4

+

ion dissociation of NH4OH is suppressed.
