在无机化学中，通常是以反应中是否发生了电子转移来作为判断氧化还原反应的依据。即在化学反应中，元素失去电子，化合价升高，称之为被氧化，由此元素组成的物质称为还原剂。反之，若元素得到电子，化合价降低，称之为被还原，该原子所组成的物质称为氧化剂。典型例子：... In inorganic chemistry, it is usually based on whether or not electron transfer occurs in the reaction as a basis for determining the redox reaction. That is, in a chemical reaction, the element loses electrons and the valence rises. This is called oxidation, and the substance consisting of this element is called a reducing agent. Conversely, if the element gets electrons, the valence is reduced, which is called reduction. The substance that the atom consists of is called an oxidant. typical example:...
