Occurrence: Zinc is not found in the free state in nature. It is found in the form of various ores in the joint stage. It gets abundant in the form of zinc bland and calamine ore.
Extraction of zinc: Extraction of zinc metal is done mainly from its sulfide ore zinc blade (Zns).
Physical properties of zinc: This blue is white, solid and brittle. Its melting point is 419 ° C, boiling point 920 ° C and specific gravity 7.1. At 100 ° C – 150 ° C, it is tensile and fatal. It is a good conductor of heat and electricity.
Chemical properties of zinc: It releases H2 gas by reacting with dilute hydrochloric acid. By releasing this diluted sulfuric acid, it releases SO2 gas. It releases nitrous oxide (N2O) gas by reacting with cold and dilute nitric acid. It releases NO2 gas by concentrating with concentrated nitric acid. It frees H2 gas when heated with a combination NaOH or concave KOH solution and becomes a gymnastic. It supersedes copper with the solution of copper sulphate.
Usage of zinc: (i) Used in the laboratory as granulated zinc and zinc powder. (ii) It is used in making galvanize iron to prevent iron corrosion. (iii) Zinc is used in making alloys in Brass, Bronze, German Silver etc. (iv) In the extraction of silver and gold (v) in making warranty in the war zone

Zinc Sulphate: It is also called white potty or white vitriol. It’s colorless and vibrant solids. It is used in the construction of lithopon and in the production of color and calico printing.
Zinc Oxide: It is a amphoteric oxide. This is called Philosopher’s Wool. It is found in nature as a zinc or red zinc ore. This is white sterile powder. It is insoluble in water. It works to make plasters, creams, artificial teeth etc. Zinc oxide coloring also comes in the works. So it is called Zinc white.
Lithopone: A mixture of zeric sulfide (Zns) and barium sulphate (BaSO4) is called lithopone. Lithopone is obtained by reacting between zeroes sulfate and barium sulphide. It is very useful for dyeing work, because it does not have any effect on hydrogen sulfide gas.
Zinc Sulphide: It is found in nature in the form of Zinc Bland. This water is insoluble white solid. It displays the properties of phosphorescence. It works in making phosphorescence curtains.
Zinc Phosphide: Zinc phosphide is used as rat poison.
Zine Chloride: This is a white solvent solid, which is quite soluble in water. It produces a jacket by reacting to alkali. Anaerobic zinc chloride is used as water absorber. Geic chloride is coated on it to protect wood objects from insects.
Zinc Carbonate: This is a saturated white solid. It is insoluble in water. Carbon dioxide gas emits when it is heated. Dermatochemistry is made from zinc carbonate.
