A simple buffer can be prepared by mixing significant amounts of a weak acid and its conjugate base.

Question

Quizplus · Accepted Answer

This is true. A buffer solution can be prepared by mixing a weak acid and its conjugate base in relatively equal amounts. This is because when there are equal amounts of the weak acid and its conjugate base, any added acid or base will react with both species and the pH of the solution will not change significantly.
