Properties
8/3 Moles water per mole cadmium sulfate, odorless,
monoclinic crystals. On heating loses water above 40°, forming monohydrate
by 80°. Does not become anhydrous on further heating. d 3.09. Freely sol in water. Almost
insol in ethanol, acetone, ammonia, ethyl acetate. Poisonous. Emits toxic Cd and SOx fumes when heated
to dec.Caution
