Answer:
Option A, Donates H+ ions when conditions become too basic and accepts H+ ions when conditions become too acidic
Explanation:
Buffer solutions have the ability to maintain stability of pH of the solution. They resist any changes in the pH of the solution on addition of an acid or a base component or solution.
Every buffer solution has a buffer capacity and range. Buffer capacity depicts the amount of acid or base solution is required to change the pH of the solution by 1 .
Hence, option E is correct
