A solution containing a buffer has an initial pH of 8.78.If a student adds 5 drops of HCl(aq)to this solution,what would be a reasonable pH for the resulting solution?

Question

Quizplus · Accepted Answer

Buffers are designed to resist changes in pH when small amounts of acid (like HCl) or base are added. Therefore, the pH will change slightly but not dramatically from the initial pH of 8.78. Option C, 8.64, represents a small decrease in pH consistent with the addition of a small amount of acid to a buffered solution.
