电化学试题的常见题型主要包括:将新型电源作为载体,考查原电池的原理及应用;考查电解池的工作原理,书写电极反应和电解反应方程式。下面将其常见的几种考查方式进行归纳解析,希望对师生的高考备考有所帮助。一、判断池型判断池型时,若一池中电极和电解质溶液之间存在自发的氧化还原反应,则其为原电池。若电极与外接电源相连则为电解池。通常阳极是与外电源正极相连,发生氧化反应;阴极与外电源负极相连,发生还原反应;电解池的阳极发生氧化反
The common types of electrochemical test questions include: the new power supply as a carrier to examine the principle and application of the original battery; test the working principle of the electrolytic cell, writing electrode reaction and electrolytic reaction equation. The following several common ways to summarize their analysis, hoping to prepare for the college entrance examination for teachers and students to help. First, to determine the pool type to determine the pool type, if there is a pool of spontaneous oxidation and reduction reaction between the electrode and the electrolyte solution, it is the original battery. If the electrode is connected with the external power supply for the electrolysis cell. Usually the anode is connected with the positive pole of the external power source, the oxidation reaction occurs; the cathode is connected with the negative pole of the external power source, and a reduction reaction occurs; the anode of the electrolytic cell undergoes oxidation reaction
