About 30cm3 of 1 mol dm-3 nitric acid is put in a beaker and is heated. Using a spatula, copper(II) oxide is added a little at a time, to the hot nitric acid while stirring continuously with a glass rod. The addition of copper(II) oxide is stopped when some black solids remain undissolved.
The mixture is filtered to remove the excess copper(II) oxide.
The filtrate is evaporated until a saturated solution is formed. The saturated solution is then allowed to cool to room temperature.
This is the copper(II) nitrate salt formed.
