溶液酸度是化学反应的重要条件之一,许多反应必须在一定的酸度下才能进行或进行得比较完全。例如,沉淀形成或溶解、氧化还原反应、络合物形成、以及元素的分离等。对所要求的溶液酸度,使用单纯的酸和碱不难调节所需要的酸度,但在反应过程中,一般 The acidity of a solution is one of the important conditions for a chemical reaction. Many reactions must be performed at a certain degree of acidity or performed more completely. For example, precipitation formation or dissolution, redox reaction, complex formation, element separation, and the like. For the required acidity of the solution, it is not difficult to adjust the required acidity using simple acids and bases, but in the course of the reaction, generally
