What is a buffer?


a solution that can receive moderate amounts of acid or base with little change in pH


a solution that neutralizes acids and increases the pH of bases


a solution that neutralizes bases and drops the pH of acids


a solution that can receive any amount of acid or base to form a neutral solution

Buffers maintain a pretty stable pH level, resisting any large changes. When introduced to a base, it will act as an acid to counteract it, and vice versa.

Answer : The correct option is, a solution that can receive any amount of acid or base to form a neutral solution.

Explanation :

Buffer : It is defined as a solution which prevent the any changes in the pH on the addition of an acidic and basic components.

Or we can say that, buffer is a solution that maintain the pH of the solution by adding the small amount of acid or a base.

As we know that there are two types of buffer which are acidic buffer and basic buffer.

Acidic buffer : It is defined as the solution that have the pH less than 7 and it contains weak acid and its salt. For example : Acetic acid (weak acid) and sodium acetate (salt).

Basic buffer : It is defined as the solution that have the pH more than 7 and it contains weak base and its salt. For example : Ammonia (weak base) and ammonium chloride (salt).

Hence, the correct option is, a solution that can receive any amount of acid or base to form a neutral solution.
