Health code 2: Intense or continued but not chronic exposure could cause temporary incapacitation or possible residual injury. Reactivity code 1: Normally stable, but can become unstable at elevated temperatures and pressures. The structure of the solid pentahydrate reveals a polymeric structure wherein copper is again octahedral but bound to four water ligands. For laboratory use, copper sulfate is usually purchased.
Anhydrous Copper sulfate is 39. 81 percent copper and 60. 19 percent sulfate by mass, and in its blue, hydrous form, it is 25. The second dehydration step occurs with the final two aqua groups are lost.
Complete dehydration occurs when the only unbound water molecule is lost. When water is then added to the anhydrous compound, it turns back into the pentahydrate form, regaining its blue color, and is known as blue vitriol. In an illustration of a “single metal replacement reaction”, iron is submerged in a solution of copper sulfate. In high school and general chemistry education, copper sulfate is used as electrolyte for galvanic cells, usually as a cathode solution. However, some fungi are capable of adapting to elevated levels of copper ions.
Copper ions are highly toxic to fish, however. Most species of algae can be controlled with very low concentrations of copper sulfate. In industry copper sulfate has multiple applications. Copper sulfate can be used as a coloring ingredient in artworks, especially glasses and potteries. Copper sulfate is also used in firework manufacture as a blue coloring agent, but it is not safe to mix copper sulfate with chlorates when mixing firework powders. It corrects copper deficiencies in the soil and animals and stimulates farm animals’ growth. In decoration, copper sulfate adds color to cement, metals and ceramic.
Some batteries, electrodes and wire contain copper sulfate. It is used in printing ink and hair dye and it creates a green color in fireworks. Several chemical tests utilize copper sulfate. Lowering a copper etching plate into the copper sulfate solution. It is now considered too toxic for this use.
Copper sulfate is used as an anti-fungal. Copper sulfate is used as an anti-fungal agent to protect seeds against fungus. London with 75,000 liters of copper sulfate solution. It often highlights the green tints of the specific dyes. It can be produced by dehydration of the normally available pentahydrate copper sulfate.
