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
CAS:584-08-7
EC: 209-529-3

• 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.
