Question

What is the colour of copper (II) chloride formed in the given chemical equation CuO + 2HCl  CuCl2 + H2

Answer 1

Answer:

Blue-Green solution

Explanation:

CuO is a base. HCl is an acid. The HCl neutralises the CuO to form CuCl2(aq) and H2O(l). CuCl2(aq) is a blue-green solution

Answer 2

Answer:

The equation in question is wrong.

The correct equation is,

CuO      +   2HCl              ===>   CuCl₂      +       H₂O

Copper      Hydrochlroic           Copper(II)         Water

Oxide        Acid                          chloride

CuCl₂ will have a colour Blue-green in the solution.

Copper(II) Chloride=>

1. Molecular Weight is 134.45 g/mol

2. Light brown solid.

3. Having octahedral geometry due to the Jahn-Teller effect

4. Paramagnetic in nature.

5. Can be toxic.

6. Used in pyrotechnics as a blue/green coloring agent.

7. Prepared by chlorination of copper commercially.
