How Is Nickel Ii Cyanide Synthesized?

Nickel(II) cyanide can be synthesized by mixing a solution of nickel(II) chloride with a solution of potassium cyanide in water. The resulting precipitate is separated via filtration and washed with distilled water to remove any residual impurities. The chemical equation for the reaction is:

NiCl2 + 2KCN → Ni(CN)2 + 2KCl

It's important to note that cyanide is a highly toxic substance and proper safety precautions, such as wearing protective gear and ensuring adequate ventilation, should be taken when working with it.
