Assertion : Salting out action of sodium soap in oresence 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)`.A. If both assertion and reason are true and the reason is the correct explantion of the assertion.B. If both assertion and reason are true but reason is not the correct explanation of the assertion.C. If assertion is true but reason is false.D. If assertion is false but reason is true. |

Answer» Correct Answer - D `RCOONa rarr RCOO^(-)+Na^(+)`, In presence of `NaCl`, `[Na^(+)]` increases and `[RCOO^(-)][Na^(+)]` exceeds thatn `K_(sp)` of `RCOONa. |
