As a natural subject, do you know the relevant chemical information? It is both abstract and concrete, and the content of its subject thought is rich and colorful. Chemical is a science, which extends to philosophy, which can be regarded as the mother of all science. In other words, the end of chemistry is philosophy! Let's look at the philosophical ideas contained in the middle school chemical news.
The thought of unity of opposites is an important content of philosophy. It is ubiquitous in middle school chemistry. This thought embodies the mutual compliance between the two opposite aspects of the same problem. Using this idea is very helpful to the understanding, mastery and application of chemical knowledge. The redox reaction in senior high school chemistry is the concrete embodiment of this idea. Oxidation and reduction are two aspects of a redox reaction, which comply with and oppose each other. In other words, in a redox reaction, there are not only the gain and loss of electrons, but also the rise and fall of valence, both oxidants and reductants, both oxidation products and reduction products, oxidation reaction, reduction reaction and so on. The establishment of this idea is very helpful for students to learn redox reaction. In addition, in other aspects, such as the fracture and formation of chemical bonds, the metallicity and non metallicity of elements, the positive and negative poles and Yin and Yang poles in electrochemistry, etc., all include the idea of unity of opposites.
