Assertion : Salting out action of sodium soap in presence of `NaCl` is based on common ion effect.
Reason : Salting out action of soap is based on the fact that as the concentration of `Na^(+)` increases, the `RCOONa` shows precipitation because `[RCOO^(-)][Na^(+)]gtK_(sp)`.

Options

A. S is correct but E is wrong.
B. S is wrong but E is correc.
C. Both S and E are correct and E is correct explanation of S.
D. Both S and E are correct but E is correct explanation of S.

Answer

B

Explanation

`RCOONararrRCOO^(-)+Na^(+)`,
In presence of `NaCI, [Na^(+)]` increases and `[RCOO^(-)][Na^(+)]` exceeds than `K_(SP)` of RCOONa.
