Copper sulfate pentahydrate

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, 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.

Fire Hazard

Literature sources indicate that Copper sulfate pentahydrate is nonflammable.

Definition

ChEBI: Copper(II) sulfate pentahydrate is the pentahydrate of copper(2+) sulfate. A bright blue crystalline solid. It is a hydrate and a metal sulfate. It contains a copper(II) sulfate.

Application

Copper(II) sulfate pentahydrate has been used:as an additive in trace element solution preparation in solid glucose minimal media.as a component of adamsII solution in Pneumococcal media.in the preparation of alginate gel for drug encapsulation.Copper(II) sulfate is an inorganic Lewis acid commonly used to promote acid catalyzed organic reactions. It is used as a reagent for the synthesis of copper carbenoids. It can also act as an effective redox catalyst in combination with other mixed oxidizing systems.Copper Sulfate Pentahydrate Fine Crystals serve as the main ingredient for manufacturing Bordeaux and Burgundy mixtures that are used as algaecides, both on the farm and to ensure safe water supplies. Bordeaux mixtures are also employed to adjust and maintain copper deficient soils to optimum levels.

General Description

Blue crystalline granules or powder. Melting point 110°C (with decomposition). Non-combustible. Nauseating metallic taste. Odorless. White when dehydrated.
