Assertion : Colloidal solution is ele...

Assertion : Colloidal solution is electrically neutral. Reason : Due to similar nature of the charge carried by the particles, they repel each other and do not combine to form bigger particles.

A

If both (A) and (R) are correct, and (R) is the correct explanation of (A)

B

If both (A) and (R) are correct, but (R) is not the correct explanation of (A)

C

If (A) is correct, but (R) is incorrect

D

If (A) is incorrect, but (R) is correct

Text Solution

Verified by Experts

The correct Answer is:
B
The particles of the colloids are electrically charged and carry positive or negative charge. The dispersion medium has an equal and opposite charge making the system neutral as a whole.
