Inorganic Chemistry

Inorganic chemistry is the science of experimental research and theoretical explanation of the properties of all elements and their compounds and their reactions except hydrocarbons and their derivatives.

Elementary Substance

A substance composed of atoms of an element that exists in a stable form in a free form is called an Elementary Substance. The element must be a pure substance composed of one element, so the mixture cannot be element. Generally speaking, the nature of the element is closely related to the nature of its elements.

Non-metallic Minerals

Non-metallic minerals refer to minerals that do not have metallic or semi-metallic luster, are colorless or have various light colors, are transparent or translucent under a 0.03 mm thick sheet, and have poor electrical and thermal conductivity. It includes most of the oxygenated salt minerals and some oxide and halide minerals. As an important material basis for human survival and development, non-metallic minerals have long coexisted harmoniously with humans and are closely related to the environment, ecology and health.

Oxides and Peroxides

Oxides are compounds (of course they must be pure). Its composition contains only two elements, one of which must be oxygen, the other if it is a metal element, it is called a metal oxide; if the other is not a metal element, it is called a non-metal oxide. Peroxide refers to a compound containing peroxy-O-O-. It can be regarded as a derivative of hydrogen peroxide, which contains peroxide ions in its molecules. Peroxides are divided into inorganic peroxides and organic peroxides.

Inorganic Acid

Inorganic acid, also known as mineral acid, is a general term for acids in inorganic compounds. Inorganic acids are generally inorganic compounds that can dissociate hydrogen ions. A compound consisting of hydrogen and a non-metallic element or group. According to the composition, inorganic acids can be divided into oxyacids, anaerobic acids, complex acids, mixed acids, superacids, etc. According to the degree of dissociation, they can be divided into strong acids and weak acids, and according to the ionizable hydrogen ion The number is divided into monobasic acid, dibasic acid and polybasic acid.
