Which statement about buffer solutions is not true?
A) they resist changes in pH upon addition of small quantities of acid or base
B) they consist of approximately equimolar quantities of a weak acid and its conjugate base
C) they consist of approximately equimolar quantities of a weak base and its conjugate acid
D) their acid and base components must react with each other to form new products
E) their pH changes only slightly if the solution is diluted by a factor of 10 with pure water

The statement "their acid and base components must react with each other to form new products" is not true. In a buffer solution, the weak acid and its conjugate base (or weak base and its conjugate acid) are present in equilibrium, but they do not necessarily react with each other to form new products.
