Product Description

Product Description

Colorless cubic or tetragonal crystals. Sensitive to moisture. Solubility in water (g/ 100mL) : 4 at 15ºC, 4.3 at 25ºC, 5 at 100ºC, insoluble in ethanol. Partial hydrolysis of aqueous solution shows an alkaline reaction. The newly prepared saturated solution has a pH of 7.4. Its aqueous solution can make the glass hairy, but its dry crystals or powders can be stored in glass bottles
