Copper sulfate pentahydrate Usage And Synthesis

Chemical Properties

Blue Solid

Chemical Properties

Copper sulfate is a greenish-white crystalline solid; the pentahydrate is Blue powder or granules, or ultramarine crystalline solid.

Uses

Used as a source of Cu2+ ions

Uses

Anhydr salt for detecting and removing trace amounts of water from alcohols and other organic Compounds; as fungicide. Pentahydrate as agricultural fungicide, algicide, bactericide, herbicide; food and fertilizer additive; in insecticide mixtures; in manufacture of other Cu salts; as mordant in textile dyeing; in preparation of azo dyes; in preserving hides; in tanning leather; in preserving wood; in electroplating solutions; as battery electrolyte; in laundry and metal-marking inks; in petroleum refining; as flotation agent; pigment in paints, varnishes and other materials; in mordant baths for intensifying photographic negatives; in pyrotechnic compositions; in water-resistant adhesives for wood; in metal coloring and tinting baths; in antirusting compositions for radiator and heating systems; as reagent toner in photography and photoengraving; etc.

Definition

A green mineral consisting of copper(II) carbonate and hydroxide (CuCO3.Cu(OH)2). It is used as an ore and a pigment.

Definition

malachite: Apresumptive test for blood. Thereagent is the dye leucomalachitegreen dissolved in water along withsodium perborate (NaBO3). A bluegreencolour indicates a positive result.

Definition

ChEBI: The pentahydrate of copper(2+) sulfate. A bright blue crystalline 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, 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.

Potential Exposure

Copper sulfate is used as intermediate and wood preservative; also used in production of copper compounds; to detect and to remove trace amounts of water from alcohols and organic compounds; as a fungicide and algicide; in veterinary medicine and others.

Shipping

UN3288 Toxic solids, inorganic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required. UN3077 Environmentally hazardous substances, solid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous hazardous material, Technical Name Required.

Incompatibilities

Aqueous solution is an acid. May form explosive materials on contact with acetylene and nitromethane. Incompatible with strong bases; hydroxylamine, magnesium; zirconium, sodium hypobromite, hydrazine.

Waste Disposal

Copper-containing soluble wastes can be concentrated through the use of ion exchange, reverse osmosis, or evaporators to the point where copper can be electrolytically removed and sent to a reclaiming firm. If recovery is not feasible, the copper can be precipitated through the use of caustics and the sludge deposited in a chemical waste landfill Add soda ash to waste CuSO4 solution; let stand 24 hours. Decant and neutralize solution before flushing to sewer. Landfill sludge.
