Zinc chloride is known to have four crystalline hydrates and at least one basic salt, such as ZnOHCl. Crystalline hydrates of zinc chloride, with n = 4 as the main component, can be precipitated from aqueous solutions of zinc chloride, while other forms have n values of 1, 1.5, 2.5, an...
The purification of chloride is simple due to the existence one oxidation state (2+) of zinc. Purification can be done through recrystallization from dioxane (hot). The purification of anhydrous zinc chloride can be done through sublimation with hydrogen chloride gas, followed by the subsequent ...
chloride as a flux for soldering - it dissolves oxide coatings exposing the clean metal surface. Typically this flux was prepared by dissolving zinc foil in dilute hydrochloric acid until the liquid ceased to evolve hydrogen; for this reason, such flux was once known as killed spirits or "...

Definitionzinc chloride: A white crystalline compound, ZnCl2. The anhydrous salt, which is deliquescent, can be made by the action of hydrogen chloride gas on hot zinc; r.d. 2.9; m.p. 283°C; b.p. 732°C. It has a relatively low melting point and sublimes easily, indicating that ...
The thermodynamics of zinc sulphide transport in hydrogen chloride by modified entrainmentThe equilibrium ZnS(c, sphalerite) + 2HCl(g) = ZnCl2(g) + H2S(g) was studied by modified entrainment in the temperature range 1023 to 1263 K and the free energy equation, ΔG0/J mol1 = (95060 ± ...
