Question

Classify bases on the basis of their strength.

Answer 1

On the basis of strength, bases can be classified as following:

(i) Strong alkalis or bases: The alkalis or bases which undergo complete ionisation in aqueous solution are known as strong alkalis or bases.

Example– $\text{NaOH}$

(ii) Weak alkalis or bases:

The alkalis or bases which undergo only partial ionisation in aqueous solution are known as weak alkalis or bases.

Example– ${\text{NH}}_{4}OH$
