Product Description

Product Description

Descriptions

It is white fine particle crystal or powder, hygroscopic, easily soluble in water, and neutral in aqueous solution. Soluble in glycerol, insoluble in alcohol. Exposure to air will gradually absorb 1 molecule of water. The anhydrous substance with high purity and fine particles is called sodium powder. Sodium sulfate can form heptahydrate and decahydrate, heptahydrate (Na2SO4.7H20) is a white rhombic crystal. It becomes anhydrous when heated to 24.4°C. Sodium sulfate is reduced to sodium sulfide when it reacts with carbon at high temperatures.
