- Substance
Sodium thiocyanate appears as a white crystalline powder that is hygroscopic in nature, meaning it readily absorbs moisture from the air. It has a melting point of approximately 287 °C and a boiling point of around 760 °C. The compound is soluble in water, with a solubility of about 1,000 g/L at 20 °C, and it has a density of 1.2 g/cm³. Its odor is faintly reminiscent of mustard oil, which is characteristic of thiocyanate compounds.
