Question

What is a buffer and how do they function in a chemical reaction?​

Answer 1

Answer:

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 amounts of added acid or base., thus maintaining the pH of the solution relatively stable. This is important for processes and/or reactions which require specific and stable pH ranges.

Explanation:

Answer 2

A buffer is an aqueous solution that has a highly stable pH. A buffering agent is a weak acid or weak base that helps maintain the pH of an aqueous solution after adding another acid or base. ... Similarly, adding water to a buffer or allowing water to evaporate will not change the pH of a buffer.
