Based on this information, I think that the green pool water is the result of excessive copper sulfate in the water. Copper sulfate -- copper(II) sulfate or copper sulfate pentahydrate -- is a ...

The process, formally known as “laser-induced backside wet-etching,” uses a laser to blast away at a tank of copper sulfate. When a piece of glass is suspended on the surface of the solution ...

is used to separate a soluble solid from a liquid. For example, copper sulfate is soluble in water – its crystals dissolve in water to form copper sulfate solution. During evaporation ...

sulfate and blue hydrated copper(II) sulfate. The equation for this is: Note that the removal of water from hydrated copper(II) sulfate requires heat, and so is an endothermic process. The reverse ...
