In a saturated solution of AgCl, addition of NaCl is made drop by drop in excess. Which graph correctly represents the change?

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
B
`[Ag ^(+)] [Cl ^(-)] = K _(sp ) or [Ag ^(+)] = (K_(sp ))/( [Cl ^(-)])`
if `[Cl ^(-)],` increase, then too have `K _(sp)` constant and thus `[Ag ^(+)]` decreases Also after surficient addition
of `[Cl ^(-)] , [Ag ^(+)] ` will become almost constiant
