一、电化学中四个极正负极是根据物理学上的电极电势高低而规定的,多用于原电池.正极电极电势高,是流入电子(外电路)的电极;负极电极电势低,是流出电子(外电路)的电极.阴阳极是针对电解池或电镀池来命名的.阳极是指与电源正极相连,发生氧化反应的电极;阴极是指与电源负极相连,发生还原反应的电极.二、电化学中四个池1.原电池:化学能转化为电能的装置.除燃料电
First, the four very positive and negative electrochemical electrochemical electrode is based on the level of the provisions of the high and low, and more for the original battery. Positive electrode high potential is the flow of electrons (external circuit) of the electrode; negative electrode potential is low, is Electrode out of the electronic (external circuit.) Yin and Yang for the electrolytic cell or plating pool to name the anode is connected to the positive power supply, the oxidation reaction occurs; the cathode is connected to the negative electrode, the reduction reaction electrode. Second, the four electrochemical cells 1. The original battery: chemical energy into electrical energy devices. In addition to fuel electricity
