Question

A small amount of acid is added to a buffer solution, the ph of the solution will

Answer 1

Increase due to rising ph

Answer 2

A small amount of acid is added to a buffer solution, the ph of the solution will

A. increase

B. decrease  

C. stay about the same

D. become neutral

correct option is option C

Buffer is a solution which can resist the change in pH with small addition of acid or base.

Hence a small amount of acid when added to a buffer solution will not change its pH,or its pH remains the same.
