Potassium carbonate is a white salt, soluble in water and forms strong alkaline solutions, i.e. it is a basic salt. It is commonly used in the manufacture of glass and soaps.
IDENTIFICATION AND PROPERTIES POTASSIUM CARBONATE
Name: Potassium Carbonate
- Appearance: granular solid or white powder
- Odour: Odourless
- pH (aqueous solution): 11,6
- Melting point: 891ºC
- Flammability (solid/gas): Not considered pyrophoric or flammable in contact with water.
- Vapour density (air=1): Based on the high melting point (891°C), the vapour pressure is considered negligible at ambient conditions.
- Relative density (19ºC): 2.43
- Solubility in water (20ºC): 900-1105 g/l
- Self-ignition temperature. It is not necessary to carry out the study as previous results do not show self-ignition of the substance up to 400°C.
- Decomposition temperature: >400ºC
- Explosive properties: There are no chemical groups in the molecule that indicate explosive properties.
- Oxidising properties: There are no structural groups in the molecule that react exothermically with combustible material.
