Cyanides Are Available In Multiple Chemical Forms:
Sodium Cyanide (NaCN)
White Crystalline Solid, Highly Soluble In Water.
Used In Mining (gold, Silver), Organic Synthesis, And Electroplating.
Potassium Cyanide (KCN)
White Crystalline, Highly Soluble.
Applications: Similar To NaCN, Often In Gold Extraction Or Chemical Labs.
Hydrogen Cyanide (HCN)
Colorless, Extremely Toxic Gas Or Liquid At Low Temperature.
Used In Chemical Synthesis (plastics, Fumigation).
Calcium Cyanide (Ca(CN)₂)
Grayish-white Powder.
Commonly Used In Mining, Metallurgy, And Fertilizer.
