In a dry evaporating dish 7.50 g solid copper (II) sulfate pentahydrate was dissolved in 30.0 ml of deionized water at 60.0 o C. While stirring, slowly 1.23 g of iron powder was added to the solution. The solution was allowed to sit for 10 minutes and then the liquid from the evaporating dish was decanted. The solid was washed with cold deionized water and dried on a hot plate. The weight of the dry solid in the evaporating dish...
