CuO+HCI->CuCI2…

The reaction you are referring to is the reaction between copper(II) oxide (CuO) and hydrochloric acid (HCl). The balanced chemical equation for the reaction is as follows:

\[ \text{CuO} + 2 \text{HCl} \rightarrow \text{CuCl}_2 + \text{H}_2\text{O} \]

Explanation:

• Reactants:

  • Copper(II) oxide (CuO), which is a solid.
  • Hydrochloric acid (HCl), which is an aqueous solution.

• Products:

  • Copper(II) chloride (CuCl₂), which is also an aqueous solution.
  • Water (H₂O).

Reaction Steps:

1. When CuO is added to HCl, it reacts to form CuCl₂ and water.
2. The copper(II) oxide acts as a base, reacting with the hydrochloric acid, which is an acid.

Important Points:

• Ensure to follow laboratory safety protocols if performing this reaction.
• This reaction is typical for the neutralization of metal oxides by acids.
