Question

What happens to the pH when a a small amount of acid is added to a buffered solution?

A.the pH goes up to 14.

B.The pH goes down to 1.

C.The pH stays about the same.

D.The pH goes to 7.

Answer 1

C.The pH stays about the same.

Step-by-step explanation:

Buffer reactions maintain stable pH of solutions.

Answer 2

C. The pH stays about the same.

• A buffered solution resists changes in pH upon addition of small amounts of acid or base. The buffer system in the solution will react with the added acid, keeping the pH relatively constant
