ZnCl is not the exact chemical formula of zinc chloride, but a misplaced chemical formula. The correct chemical formula of zinc chloride is ZnCl2, because Zn is divalent and chlorine is also divalent. I don't know why ZnCl has so many searches on Google, and today I want to correct this mistake.
Zinc chloride, as an inorganic salt, has a relatively simple production process. Filter with zinc soil or zinc slag, then add a large amount of hydrochloric acid to react chemically to obtain zinc chloride solution. The appearance of zinc chloride solution is colorless and looks like water on the surface. The concentration is generally 40--68%, and it is widely used in zinc-manganese dry batteries, oil extraction, biomedicine, etc.
