Experimental Properties:Loses 2H2O @ 30 °C, 2 more H2O @ 110 °C; becomes anhydrous by 250 °C; efflorescent in air.|LOSING WATER BY CRYSTALLIZATION @ 110 °C TO FORM WHITE MONOHYDRATE, CUSO4.H2O|Dielectric constant: 6.60 @ room temperature|Slowly effloresces in dry air or above 30.6 °C with the formation of the trihydrate; at 88-100 °C the trihydrate is produced more quickly; above 114 °C the monohydrate is formed, and between about 245 and 240 °C, the anhydrous product copper(II) sulfate results.
Air and Water Reactions:Slowly effloresces in air. Water soluble.
Reactive Group:Salts, Acidic
Reactivity Profile: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 (NTP, 1992). Both act as acidic salts, corrode metals and irritate tissues.
Corrosivity:Very corrosive to plain steel.
