原电池电极反应式的书写是一大难点,如何较轻松地解决这一难点,关键是通过总反应判断发生氧化和还原反应的物质,将氧化与还原反应分开,结合反应环境,便可得到两极反应.本文将介绍原电池电极反应式书写技巧.1)原电池两极的判断:先分析电池反应中有关物质元素化合价的变化,确定原 The primary battery electrode reaction writing is a major difficulty, how to more easily solve this problem, the key is to determine the total reaction of oxidation and reduction reaction substances, oxidation and reduction reaction separately, combined with the reaction environment, can be bipolar Reaction.This paper will introduce the original cell electrode reactive writing skills.1) the original cell bipolar judgment: first analysis of the battery reaction valence of the relevant elements of the valence change, determine the original
