How to make copper oxide crystals

Published 02.01.2019

In this experiment an insoluble metal oxide is reacted with a dilute acid to form a soluble salt. Copper(II) oxide, a black solid, and colourless dilute sulfuric acid react to produce copper(II) sulfate, giving a characteristic blue colour to the solution. Experimental work can. There are a number of ways that you could make copper sulfate crystals in Add a spatula of copper oxide powder to the acid and stir with a glass rod. Continue. It is a combination of copper oxide and sulfuric acid. Copper sulfate is also often used to grow brilliant blue crystals as a fun science experiment.

Copper(II) oxide or cupric oxide is the inorganic compound with the formula CuO. A black solid Copper(II) oxide belongs to the monoclinic crystal system. The copper atom is coordinated by 4 oxygen atoms in an approximately square planar configuration. Set up a Bunsen burner, tripod and gauze. and gently warm the solution for a minimum of 5mins and stir, CAREFULLY! DO NOT BOIL IT!. You didn't say which copper oxide you are dealing with – copper(I) oxide or copper(II) oxide. Here are the results for both: Case 1: CuO +.

Phase-pure cuprous oxide (Cu2O) crystals are difficult to grow since crystals and their inclusions, owing to anisotropic surface energy, do not.
