    Gold (I) potassium cyanide is a high purity, commonly used form of gold found in the majority of gold plating electrolytes. In this salt the gold is complexed with cyanide in order to make it a water soluble specie in which gold is 68.3% of its weigh. The product is available in 100 grams of powder containing 68.3 grams of gold.

    Sodium cyanide is water reactive. Sodium cyanide decomposes on contact with acids, acid salts, water, moisture, and carbon dioxide, producing highly toxic, flammable hydrogen cyanide gas. Sodium cyanide solution in water is a strong base; it reacts violently with acid and is corrosive. Sodium cyanide is incompatible with strong oxidants.
