CHM PAPER 6 doubt
Copper(II) oxide and carbon are both black solids. Copper(II) oxide reacts with dilute sulfuric
acid to form aqueous copper(II) sulfate. Carbon does not react with dilute sulfuric acid.
You are given a mixture of copper(II) oxide and carbon and access to dilute sulfuric acid.
Plan an experiment to investigate the percentage of copper(II) oxide in the mixture.
