Question

Is the purpose of a buffer system to keep a solution neutral? If not, what is the purpose?

Answer 1

The purpose of an buffer is to maintain the pH of the given solution around a given value.

Answer 2

A buffer is a solution that can resist pH change upon the addition of an acidic or basic components.it is able to neutralize small amount of added the acidic or basic, thus maintaining the pH of the solution relatively stable.this is important for processes and reactions which require specific and stable pH ranges.
