Description
| Formula | KHCO3 |
| Molecular weight | 100 |
| CAS | 298-14-6 |
| Properties | Colorless and transparent crystals. The relative density is 2.17. It is stable in the air, soluble in water, forming a slightly alkaline solution, but insoluble in alcohol. The solution can not react with magnesium salt yielding precipitate of alkaline salt. It begins to decompose at 100°C and completely decomposes and turns into Potassium carbonate losing carbon dioxide and water at 200°C. |
| Uses | Used as a raw material producing potassium carbonate, potassium acetate and potassium arsenite. Also it is a fire-extinguishing agent for oil and chemicals, used in medicine and baking powder. |
| Packing | In 25/50/500/1000kg PP/PE bag or on customer request. |
| Storage | Store in dry and ventilated warehouse away from moisture. Don't store goods outside or expose to the air. |
