Answer:

Add appropriate quantities of weak acid and its conjugate base to water

Explanation:

Explanation:

When an acid or base is added to a solution then any resistance by the solution in changing the pH of the solution is known as a buffer.

This is because a buffer has the ability to not get affected by the addition of small amounts of an acid or a base. As a result, it helps in maintaining the pH of the solution.

A buffer can be composed of a solution of weak acid or base and salt of weak acid/base.

Therefore, following statements describe a method which can be used to make a buffer.

  • Add appropriate quantities of weak acid and its conjugate base to water.
  • Partially neutralize a weak base solution by addition of a strong acid.
  • Partially neutralize a weak acid solution by addition of a strong base.
