Why is the pH of buffer solutions relatively stable when diluted or when small amounts of acid or alkali are added?

Options

  1. ADue to their high salt content
  2. BBecause of their extreme acidity
  3. CBecause of the common ion effect
  4. DDue to the presence of strong bases

Correct answer

C. Because of the common ion effect

Step-by-step solution

The stability of buffer solutions when diluted or when small amounts of acid or alkali are added is attributed to the common ion effect, as explained in the paragraph.
