Copper (I) chemistry is limited by a reaction which occurs involving simple copper (I) ions in solution. This is a good example of disproportionation - a reaction in which something oxidises and reduces itself. Copper (I) ions in solution disproportionate to give copper (II) ions and a precipitate of copper.
However, in the laboratory, experiments call for various molar concentrations as well as various required volumes. We can use molarity as a conversion factor to make solutions that have a desired concentration. Let's see how to prepare a 500.0 mL copper(II) sulfate solution that has a 0.500 M concentration.
