Question

Salting out action of soap is an application of solubility product. If true write 1, else write 0.

Answer 1

Salting out of soap: From the solution, soap is precipitated by the addition of a concentrated solution of $NaCl$.

Hence, the ionic product $\left[RCO{O}^{–}\right]\left[N{a}^{+}\right]$ exceeds the solubility product of soap and therefore, soap precipitates out from the solution.
