Introduction

Copper(II) oxide (CuO) is a black oxide of copper commonly used in educational settings to demonstrate various chemical and physical principles. Its properties and reactions can be effectively employed in laboratory activities, allowing students to gain hands-on experience with real-world applications of chemistry and physics concepts.

Properties of Copper(II) Oxide

Copper(II) oxide is a p-type semiconductor with a monoclinic crystal structure. It has a molecular weight of 79.54 g/mol, a melting point of 1,201°C, and a density of 6.315 g/cm³. These properties make it versatile for various educational experiments.

Educational Uses of Copper(II) Oxide

Chemistry Experiments

In chemistry education, Copper(II) oxide is used for illustrating oxidation and reduction reactions. One classic experiment involves the reduction of CuO using hydrogen gas:

CuO(s) + H₂(g) → Cu(s) + H₂O(g)

Students can measure the mass of CuO before and after the reaction, allowing them to calculate the percentage yield and understand stoichiometry.

Physics Demonstrations

Copper(II) oxide's semiconductor properties are useful in physics education. Experiments can demonstrate photoconductivity by measuring current changes in a CuO-coated photovoltaic cell under different light conditions. The resistivity of Copper(II) oxide can also be calculated using a four-point probe method, reinforcing concepts of electrical conductivity and material science.
