| 摘 要： | 本文用ｐＨ计测定了非中性水中几种弱酸在不同浓度时的ｐＨ值，从中找出了非中性水中不同浓度弱酸溶液ｐＮ值的表现规律。这样通过对非中性水中某一浓度弱酸溶液ｐＨ值的测定，便可从坐标图中查出或由方程式计算出在中性水中该弱酸在相应浓度下的ｐＨ值。

| Abstract: | H values of solutions of weak acids made of neutral or non-neutral waterof different concentrations were determined separately with a pH meter. lt was found thatthe pH value of a weak acid solution made of neutral water depends linearly on that madeofnon一neutral water for different concentrations. Therefore, pH value ofa weak acid solu-don made of neutral water can be calculated from that made of non一neutral waterbvfclat-ed formula or graph.Such formulae and graphs are provided in the text。 |
