Inorganic chemistry is a science that studies the composition, properties, structure and reaction of inorganic substances. It is the oldest branch of chemistry. Inorganic Inorganic Chemistry is an important branch of chemistry, which studies the chemistry of inorganic compounds. Generally, inorganic compounds refer to compounds without C-H bonds, as opposed to organic compounds, so carbon monoxide, carbon dioxide, carbon disulfide, cyanide, thiocyanate, carbonic acid and carbonate all belong to the category of inorganic chemistry research. However, the boundary between the two is not strict, and there is a great overlap, and organometallic chemistry is an example.
Matter includes all chemical elements, compounds other than carbon compounds, five kinds and several other simple carbon compounds. (Except for simple carbon compounds such as carbon dioxide, carbon monoxide, carbonic acid, carbon disulfide and carbonate, which are inorganic substances, the rest are organic substances. )
Inorganic chemistry, the earliest branch of chemistry, is a science of experimental research and theoretical explanation on the properties and reactions of all elements and their compounds except hydrocarbons and their derivatives.
In the past, inorganic substances were considered as inanimate substances, such as rocks, soil, minerals and water. Organic substances are produced by living animals and plants, such as protein, oil, starch, cellulose and urea. 1828, German chemist Willer made urea from inorganic ammonium cyanate, which broke the superstition that organic matter can only be produced by vitality and made it clear that the two substances are combined by chemical force. Now these two substances are divided according to the different components mentioned above. There are other fine classifications of chemistry.
