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