Assertion. Precipitation of soap is made...

Assertion. Precipitation of soap is made by the addition of salt (NaCl).
Reason. Presence of common ion suppresses the dissociation of weak acid.

A

If both assertion and reason are true, and reason is the true explanation of the assertion.

B

If both assertion and reason are true, but reason is not the true explanation of the assertion.

C

If aasertion is true, but reason is false.

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
C
Correct R. Salting out action of soap is based on the principle of solubility product. Common ion effect is for weak electrolytes (weak acids or weak bases).

Assertion: The pH of NH_(4)OH remains unchanged on addition of NH_(4)Cl . Reason : Addition of NH_(4)Cl suppresses the dissociation of NH_(4)OH due to common ion effect.

Assertion : Addition of HCl(aq) to HCOOH(aq) decreases the ionization of HCOOH(aq) Reason : Due to common ion effect of H^(+) , ionization of HCOOH decreased.

Asseration : The ionisation of hydrogen sulphide in water is low in the presence of hydrochloric acid. Reason : Hydrogen sulphide is a weak acid.

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) .
