Question

Buffer capacity of a buffer solution is defined as:

• A. number of moles of an acid or base when added to 100 ml of buffer solution causing no change in its pH value
• B. number of moles of an acid (or base) when added to a solution causing to change in its pH by one
• C. number of units pH that changed by adding 1 N acid or base to one litre of a buffer solution
• D. number of moles of an acid or base when added to a litre of buffer solution causing no change $ i- $ its pH value

Answer 1

Answer: (D)

Correct answer is (d) number of moles of an acid or base when added to a litre of buffer solution causing no change $ i- $ its pH value
