Question

What is the formula of potassium cyanide and explain about it.​

Answer 1

Answer:

Formula and structure: The chemical formula of potassium cyanide is KCN. Its molecular formula is CKN and its molar mass is 65.12 g/mol. It is a salt which is composed of the potassium (K+) cation and the cyanide (CN-) anion, in which the carbon atom is triply bonded to the nitrogen atom and has a negative charge.

Answer 2

Answer:

KCN is the formula of potassium cynaide.

Explanation:

In gold mining, KCN forms the water-soluble salt potassium gold cyanide (or gold potassium cyanide) and potassium hydroxide from gold metal in the presence of oxygen (usually from the surrounding air) and water:

4 Au + 8 KCN + O2 + 2 H2O → 4 K[Au(CN)2] + 4 KOH

A similar process uses NaCN to produce sodium gold cyanide (NaAu(CN2)).
