Question

Quizplus · Accepted Answer

To make a buffer using acetic acid, one should add its conjugate base. In this case, the conjugate base of acetic acid is sodium acetate, which will react with any added acid to form more acetic acid, thus maintaining the buffer pH. The other options given do not contain the conjugate base of acetic acid, so they are not suitable for making this buffer.
