Anhydrous CuSO4 can be used to remove water (an impurity) from gasoline. When the CuSO4 absorbs the water from gasoline, it becomes CuSO4.5H2O. This hydrate can be filtered off from the gasoline.

Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".
