Properties: white or light pink single crystal is fine crystallization inclined. Soluble in water, not soluble in alcohol, heating to 200 oC above starts to lose when gesso, about 280 oC gesso, 700 oC lost most of salt and water melting into no when that begins to decompose, 850 oC, because conditions different emit sulphur trioxide, sulfur dioxide, or oxygen. Density: 2.91.
Appearance and properties: white to light red tiny crystals or powder.
Melting point (℃) : 400 (H2O)
The relative density (water = 1) : 2.9500
Solubility: soluble in water, soluble in ethanol.
Main application: for making the electrolysis manganese, mn fertilizer, paint dryer, etc.
