Step 1
Buffer solution:
The solution that resists the change in pH is known as a buffer solution. The buffer solution is an aqueous solution consisting of a mixture of a weak acid and its conjugate base, or vice versa. It resists the pH changes when a small amount of strong acid or base is added to it.
