A) Common ion effect
B) Acidic buffer
C) Basic buffer
D) Both Acidic and Basic buffer​

Answer 1

Answer:

Common ion effect and basic buffer

Explanation:

Answer 2

Answer:

The equimolar quantities of both NH₄OH and NH₄Cl yield an example of a basic buffer.

Explanation:

NH₄Cl is a strong electrolyte hence, dissociates completely, NH₄OH is a weak electrolyte, that does not dissociate completely.

This solution acts as a basic buffer and maintains its pH, so it is capable of resisting the change in pH with the addition of a small amount of acid or alkali.

When a small amount of acid is added to this solution, H⁺ ions of the acid get neutralized by OH⁻ ions already present and due to which many  NH₄OH molecules get ionized to compensate for the loss of OH⁻ ions. Due to this, the pH remains maintained.

Hence, the mixture of equimolar quantities of both NH₄OH and NH₄Cl yields an example of a basic buffer. Hence, the correct option is (c) a Basic buffer.
