each question constain STATEMENT-1(Assertion ) and STATEMENT - 2 (reason). examine the statement carefully and work the correct answer accoridng to the instructions given below :
STATEMENT-1: The conversion of fresh precipitate to colloidal state is called peptization.
STATEMENT-2: It is caused by addition of common ions.

A

If both assertion and reason are true and the reason is the correct explanation 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 the assertion and reason both are false

Text Solution

Verified by Experts

The correct Answer is:
A
Common ion adsorb on the surface of precipitate. Due to repulsion between adsorbed ions, the precipitate undergo fragmentation resulting in colloidal state.
This conversion is called peptization.
