Question

to obtain pure and dry precipitate of cupric oxide (cuo) from copper sulphate solution and study its properties​

Answer 1

Explanation:

In this experiment, students react an insoluble metal oxide with a dilute acid to form a soluble salt. By reacting copper(II) oxide, a black solid, with colourless dilute sulfuric acid, they produce copper(II) sulfate with a characteristic blue colour. Students can then obtain blue copper(II) sulfate pentahydrate crystals
