What compound is formed when dilute hydrochloric acid is added to a beaker containing a small amount of copper
oxide?
Copper (II) Chloride
When dilute hydrochloric acid (HCl) is added to copper oxide (CuO), a chemical reaction occurs, forming copper (II) chloride (CuCl2) and water (H2O). The balanced chemical equation for this reaction is:
CuO + 2HCl → CuCl2 + H2O
Explanation:
- Copper oxide is a basic oxide. It reacts with hydrochloric acid, which is an acid, to form a salt and water. This type of reaction is known as a neutralization reaction.
- In this reaction, copper oxide provides Cu2+ ions, while hydrochloric acid provides Cl- ions.
- The compound formed is copper (II) chloride, as the copper is in the +2 oxidation state.
Therefore, when dilute hydrochloric acid is added to copper oxide, the compound formed is Copper (II) Chloride.
