mawonekedwe a sodium 98%
Physicochemical katundu:
1.White ufa: Kuthira madzi, kununkhira pang'ono kwa formic acid.
2. Malo osungunuka: 253 ℃
3.Kuchulukana kwachibale: 1.191g/cm3
4.Kusungunuka: Kusungunuka mu glycerin, kusungunuka pang'ono mu mowa, mowa, kusungunuka mu ether.

1.Sungani pamalo ozizira, owuma, opanda mpweya wabwino, pewani kuwala kwa dzuwa, kutali ndi kutentha, asidi, madzi, ndi mpweya wonyowa.
2.Kusindikiza kusungidwa kowuma. Zolingidwa ndi mapepala apulasitiki zilipo, ndi kulongedza zikwama zowombedwa ndi malaya. Monga mmene ambiri mankhwala kusungirako ndi mayendedwe.
