Does Pentahydrate Dissolve in Water?

The pentahydrate (CuSO4·5H2O), the most commonly encountered salt, is bright blue. It exothermically dissolves in water to give the aquo complex [Cu(H2O)6]2+, which has octahedral molecular geometry.

Why does copper II sulfate pentahydrate dissolve in water?

Copper Sulfate can dissolve in water because water is a polar solvent. ... The polarity of water leads to the positive copper ions being attracted to the oxygen atoms of water with a partial negative charge and the sulfate ions being attracted to the hydrogen atoms of water that have a partial positive charge.

How do you dissolve copper sulfate pentahydrate?

Add the copper sulfate crystals to the water in the beaker, stir briefly, and add the remaining water from the graduated cylinder to the beaker. Stir the mixture of water and salts using a glass rod until all the crystals have dissolved to form a saturated copper sulfate solution.
