题目图1装置是电解池的是( )答案:(B).这道题目看似简单.,却包含了很多知识.对原电池和电解池的识别,中学阶段是按下列原则进行的:原电池是利用自发的氧化还原反应,把化学能转化为电能的装置;电解池是在外接直流电作用下,发生非自发氧化还原反应,把电能转化为化学能的装置.一般以有无外接电 Problem Figure 1 device is the electrolytic cell is () Answer: (B) .This question may seem simple, but contains a lot of knowledge.For the identification of primary cells and electrolytic cells, secondary school phase is based on the following principles: the original Battery is the use of spontaneous oxidation-reduction reaction, the chemical energy into electrical energy device; electrolytic cell is in the role of external DC, non-spontaneous oxidation-reduction reaction, the electrical energy into chemical energy device. Generally with or without external power
