Akston Health
Chemical Properties: Blue Solid
General Description: Blue crystalline granules or powder. Melting point 110°C (with decomposition). Non-combustible. Nauseating metallic taste. Odorless. White when dehydrated.
Air & Water Reactions: Slowly effloresces in air. Water soluble.
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, and may react with beta-naphthol, sulphathiazole and triethanolamine if the pH exceeds 7. Both act as acidic salts, corrode metals and irritate tissues.
