Question
A mixture of a weak acid (say acetic acid) and its salt with a strong base (say sodium acetate) is a buffer solution. Which other pair of substances from the following may have a similar property ?
Answer: D
💡 Solution & Explanation
In option A, HCl is a strong acid along with its salt. Therefore, it is not a buffer. In option B, NaOH is a strong base along with its salt. Therefore, it is not a buffer. In option C, KOH is a strong base along with its salt. Therefore, it is not a buffer. In option D, it is a basic buffer which consists of a weak base (such as ammonium hydroxide) and its salt (such as ammonium chloride).
