The present invention relates to the technical field of chemical teaching aid, especially to a chemical inorganic compound teaching aid. The teaching aid comprises a plurality of members and connection rods, the members are hollow structures, each member is formed by a housing and an iron layer at the inner side of the housing, and the outer surface of the iron layer is adhered and fixed with theinner surface of the housing; each connection rod is formed by oppositely clamping two brace rods, one end of each brace rod is provided with one lug and one groove, the brace rods are hollow structures, and one sides, close to the convex heads of the lugs, of the internal portions of the brace rods are provided with semicircle magnetic sheets. The chemical inorganic compound teaching aid is simple in structure, low in cost and convenient to operate, solves the defects of a current model teaching aid structure, is more flexible in usage and clear in demonstration, shows the abstract chemical reaction through concrete demonstration, allows students to more easily understand, allows teachers to more easily perform teaching, can be suitable for teaching of other subjects and is high in universality.
Description
technical field [0001] The invention relates to the technical field of chemical teaching aids, in particular to a teaching aid for chemical inorganic compounds. Background technique [0002] Inorganic compounds are compounds that have nothing to do with the body (a few compounds that are related to the body are also inorganic compounds, such as water), corresponding to organic compounds, usually referring to compounds that do not contain carbon, but include oxides of carbon in the substance itself, such as carbonates , calcium salts, sulfates, nitrates, cyanides, etc., referred to as inorganic substances. Inorganic substances are mainly composed of water and inorganic salts, and there are many elements in chemistry, and various elements can be combined with each other to form thousands of organic and inorganic compounds. However, in teaching, the various compounds taught by teachers are all It is a very abstract concept. When students learn various compounds, they can only ...
