Description

Product Description

Pentahydrate Copper Sulphate 98% Price for Agriculture
copper sulphate, is the chemical compound with the chemicals formulaCuSO4. This salt 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 (CuSO4·5H2O), the most commonly encountered salt, is bright blue. Copper sulfate exothermically dissolves in water to give the aquo complex [Cu(H2O)6]2+, which has octahedral molecular geometry and is paramagnetic.

Character: It's dark blue triclinic crystal or blue crystalline powder or granule. It smells like nasty metal. It effloresces slowly in dry air. Relative density is 2.284. Above 150ºC, it loses water and form Anhydrous Copper Sulfate which absorbs water easily. It's freely soluble in water and aqueous solution is acidic. PH value of 0.1mol/L aqueous solution is 4.17(15ºC). It's freely soluble in glycerol and dilute ethanol but insoluble in pure ethanol.
Usage: It is used as nutritional supplement, antimicrobial agent, firming agent and processing aid.
Packing: It is packed with polyethylene bag as inner layer, and a compound plastic woven bag as outer layer. The net weight of each bag is 25kg.
Storage and Transport: It should be stored in a dry and ventilative warehouse, kept away from heat and moisture during transportation, unloaded with care so as to avoid damage. Furthermore, it must be stored separately from poisonous substances.
