Question

What would happen if a small amount of base were added to a bufferedsolution?A. The pH would remain about the same.B. The pH would decrease.C. The pH would increase.D. The pH would remain neutral.

Answer 1

Step-by-step explanation

A buffer is an aqueous solution containing a weak acid and its conjugate base or weak base and its conjugate acid.

Buffer solutions tend to resist a change in pH when small amounts of a strong acid or strong base are added. In other words, the pH changes very little.

Answer: A. The pH would remain about the same.
