Detailed Product Description:

A pale green powder with a nauseating metallic taste.  Soluble in water,

methanol and slight soluble in glycerol and alcohol.  Commonly used as

a dehydrating agent, in pigments, wood preservatives.  

Grade/Purity:

This is Reagent Grade material, anhydrous, with a minimum purity of 99%.

Background:

Copper sulfate is a salt that exists as a series of compounds that differ in

their degree of hydration.  The anhydrous form is a pale green or gray-white

powder, whereas the pentahydrate, the most commonly encountered salt,

occurs as bright blue crystals.

The anhydrous form occurs as a rare mineral known as chalcocyanite.  

Archaic names for copper(II) sulfate are "blue vitriol" and "bluestone".

Applications:

Often used with various acids in etching solutions for metallographic

inspections or in forensics to raise serial numbers.

Several chemical tests utilize copper sulfate.  It is used in Fehling's

solution and Benedict's solution to test for reducing sugars, which

reduce the soluble blue copper (II) sulfate to insoluble red copper (I)

oxide.  It is also used in the Biuret reagent to test for proteins.  It is

used to test blood for anemia.  The blood is tested by dropping it into

a solution of copper sulfate of known specific gravity.  Blood that contains

sufficient hemoglobin sinks rapidly due to its density, whereas blood

which does not, floats or sinks slowly.

Precautions:

Toxic by ingestion.  Strong irritant to skin and tissue.
