Question

List the changes that are observed when dil. HCl is added to a small
amount of copper oxide in a beaker. Write balanced chemical equation for
the reaction.​

Answer 1

Explanation:

copper chloride and water is formed

CuO+2HCl= CuCl2+ H2O

Answer 2

Answer:

When dilute HCl is added to a small amount of copper oxide in a beaker, a bluish green solution is formed.

Since, the metal oxides such as Copper oxide (CuO) is basic in nature, it reacts with acids such as HCl to form the corresponding salt and water. The reaction that occurs is called neutralization reaction.

The balanced chemical equation representing the above reaction is

CuO(s) + 2HCl(aq) --> CuCl2(aq) + H2O(l)
