学习氧化还原反应（Redox reaction） In the study of redox reactions, we must first understand the nature of redox reactions, and the types of redox reactions are based on their nature to solve the problem. To know which substances or elements are used as oxidants or reducing agents, which substances are the products of oxidation and which are the products of reduction. The essence of redox reaction is the gain and loss of electrons in the material. The oxidant gets the electrons and is reduced to reduced products by the reducing agent. The reductant loses the electrons and is oxidized to the oxidation products by the oxidant. Some elements of the specific performance of the material is the macro elements in valence fluctuation, some elements of oxidizer valence decreased, while reducing some of the elements in the valence of increasing agent. Remember this formula, you can understand the deep oxidation reduction reaction. The rise of the loss of oxygen, reducing, meaning reducing agent elements in valence increased, the loss of electrons is oxidation reduction; some elements used in decreasing the valence electron, reduction. All the redox reaction of the most intuitive judgment that there is a change in the valence chemical reaction, reductant and oxidant, and the pros and cons of electronic case, according to the formula can be judged. Im good at chemistry, but I dont do many problems. Chemistry in high school is very complicated, but its not difficult. To learn it well, a complete knowledge system must be constructed There are only six parts in high school chemistry: basic concepts and theories, chemical equilibria, material structures and elements, periodic laws, elements and their compounds, electrochemistry, and organic chemistry Among them, the material structure and chemical balance are the most difficult, the elements and their compounds and electrochemistry Next, the basic concepts and theories and organic chemistry are the easiest I want you to think that a chemical
