zinc cyanide is prepared by reaciot of ono mole zinc salt ( chloride /sulphate) with two mole sodium cyanide.
It can also be prepared directly by reaction of zinc oxide with hydrogen cyanide in presence of a little acetic acid.

∙ 13y agoAdd two moles of chlorine (Cl) for every mole of zinc (Zn).
Zn + Cl2 --> ZnCl2. Know that pure chlorine bonds with itself to form the chlorine gas Cl2, so practically for every mole of zinc (Zn) functional units add one mole of chlorine gas (Cl2) functional units.
