Assertion:- Animal skins are colloidal in nature Reason:- Animal skin has positively charged particles.
- A Assertion is true. Reason is true and Reason is the correct explanation for Assertion
- B Assertion is true. Reason is true but Reason is not the correct explanation for Assertion
- C Assertion is true but Reason is false
- D Assertion is false but Reason is true
Answer & Solution
Correct Answer
(B) Assertion is true. Reason is true but Reason is not the correct explanation for Assertion
Step-by-step Solution
Detailed explanation
The sol particles acquire positive or negative charge by preferential adsorption of positive or negative ions. Animal hides are colloidal in nature. When a hide, which has positively charged particles, is soaked in tannin, which contains negatively charged colloidal particles,…
