POTASSIUM NITRITE synthesis
- Product Name:POTASSIUM NITRITE
- CAS Number:7758-09-0
- Molecular formula:KNO2
- Molecular Weight:85.1038
KNO3+ Pb →KNO2+ PbO
The product is extracted with water and allowed to crystallize. Filtration separates nitrite from insoluble lead oxide.
Potassium nitrite also may be obtained by high temperature thermal decomposition of nitrate:
2KNO3→2KNO2+ O2↑.
