A buffer solution
A)is a salt solution.
B)maintains pH at 7.00.
C)is a strong base.
D)neutralizes only acids.
E)closely maintains its original pH.

Question

Quizplus · Accepted Answer

A buffer solution is defined as a solution that can resist changes in pH when small amounts of acid or base are added to it. This means that a buffer solution can maintain its original pH value by neutralizing small amounts of added acid or base. Therefore, choice E, which states that a buffer solution closely maintains its original pH, is the best answer. Choices A, B, C, and D are incorrect because a buffer solution can be made from either an acidic or basic salt, it does not necessarily maintain pH at 7.00, it is not necessarily a strong base, and it can neutralize both acids and bases depending on the composition of the buffer solution.
