Potassium Gold Cyanide

Potassium Gold Cyanide

Potassium gold cyanide (KAu(CN)2) is a compound used in electroplating, specifically in the process of gold plating onto metallic surfaces.

It is a highly toxic, colorless, crystalline substance that is soluble in water.

Known as cyanidation, the process of dissolving gold in a potassium cyanide solution yields potassium gold cyanide.

In electroplating, potassium gold cyanide serves as the source of gold ions in the electrolyte bath.

When an electric current is passed through the bath, gold ions are attracted to the surface of the object being plated, forming a thin layer of gold.

This process is widely used in jewelry making, electronics manufacturing, and decorative metal finishing.

Due to its toxicity and the environmental concerns associated with cyanide compounds, the handling and disposal of potassium gold cyanide must be carefully managed to prevent harm to human health and the environment.

Proper safety measures, including protective equipment and ventilation, are essential when working with this substance.
