Quizplus · Accepted Answer

A buffer is a solution that can resist changes in pH when small amounts of acid or base are added to it. It does this by containing both a weak acid and its corresponding base (conjugate acid-base pair). When an acid or base is added to the buffer, the weak acid will react with any added base, and the weak base will react with any added acid, effectively neutralizing the added ions and maintaining the pH of the solution. Option B is incorrect because a solution can still conduct electricity even if there is a buffer present. Option C is incorrect because buffers do not neutralize salts, they only help to maintain pH. Option D is incorrect because buffers are not able to cause high blood pressure.
