Answer:

A buffer is added to the solution so that it can resist pH change.

Explanation:

  • An aqueous solution which is a mixture of a weak acid with its conjugate alkali, or vice versa is referred to as a buffer solution or pH buffer.
  • It can resist a pH change upon addition of basic or acidic components.
  • It doesn't show a drastic pH change when a strong alkali or acid is added to it.
  • So, buffer is added to already neutral solution so that the pH change is kept minimum.
