在学习“电解”内容时,部分同学对电解过程中电解液酸碱性变化的判断感到困难.为此,特介绍以下口诀.该口诀简单实用,适用于惰性材料作电极的各种电解池.口诀: 有氢无氧增碱性,有氧无氢增酸性, 有氢有氧增原性,无氢无氧减原性.有氢指的是有氢气生成,有氧指的是有氧气生成,增碱性指的是碱性增强或酸性减弱,增酸性 When studying the “electrolysis” content, some students had difficulty in judging the change of the acidity and alkalinity of the electrolyte during the electrolysis process. Therefore, the following recipes were introduced. The formula is simple and practical, and it is applicable to various electrolytic cells with inert materials as electrodes.诀 诀 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有 有Alkalinity refers to the enhancement of alkalinity or the weakening of acidity and the increase of acidity.
