Reason : NaCl is highly soluble in water whereas AgCl is sparingly soluble.

Options

A. If both (A) and (R) are correct and (R) is the correct explanation of (A).
B. If both (A) and (R) are correct, but(R) is not the correct explanation of (A)
C. If(A) is correct, but (R) is incorrect
D. If both (A) and (R) are incorrect

Answer

B

Explanation

In presence of `NaCL, Cl ^(-)]` increases very much. Hence `[Ag^(+)]` decreaes to keep `K _(ap) = [Ag ^(+)] [Cl ^(-)]` constant.
