The document outlines an experiment to prepare a soluble salt by reacting an acid with a metal oxide. Specifically, copper(II) oxide powder is reacted with nitric acid solution. Upon heating the reaction mixture, blue-green copper(II) nitrate solution forms. The salt solution is then cooled and filtered to obtain copper(II) nitrate crystals.
