Physical properties about Copper sulfate pentahydrate are: (1)mp: 110 °C (dec.)(lit.); (2)density: 2.284; (3)vapor pressure: 7.3 mm Hg ( 25 °C); (4)storage temp: Store at RT; (5)solubility: 320 g/L (20°C); (6)Water Solubility: 320 g/L (20 oC); (7)Merck: 14,2653.

Copper sulfate pentahydrate can be dehydrated by heating. Serves as a weak oxidizing agent. Causes hydroxylamine to ignite. Gains water readily. The hydrated salt is vigorously reduced by hydroxylamine [Mellor 8:292(1946-1947)]. Both forms are incompatible with finely powdered metals. Both are incompatible with magnesium, corrode steel and iron, may react with alkalis, phosphates, acetylene gas, hydrazine, or nitromethane, and may react with beta-naphthol, propylene glycol, sulphathiazole and triethanolamine if the pH exceeds 7 . Both act as acidic salts, corrode metals and irritate tissues.

The Copper sulfate pentahydrate is harmful by inhalation, in contact with skin and if swallowed. It is irritating to eyes, respiratory system and skin.The Copper sulfate pentahydrate is very Toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment, so it should be avoided release to the environment. Refer to special instructions safety data sheet .This material and/or its container must be disposed of as hazardous waste.When you use it,wear suitable protective clothing.In case of contact with eyes, rinse immediately with plenty of water and seek medical advice.Do not breathe dust.
