Question

Activity of reaction between dilute hydrochloric acid and copper oxide a)before reaction black particles of copper interleaved HCL acid and b)after reaction to bluish green solution written in format aim material required etc​

Answer 1

Explanation:

Hint: You can try recalling a blue-green solution of a compound which has copper. The reaction taking place between HCl and copper oxide is a kind of displacement reaction. Now try to find the answer.

Complete step by step answer:

When dilute HCl reacts with copper oxide, the reaction is as follows:

CuO(s)+2HCl(aq)→CuCl2(aq)+H2O(l)

This is a double displacement reaction. The soluble copper(II)chloride is blue-green in color and is responsible for the color of the solution formed. When dilute HCl is added to a small amount of copper oxide in a beaker, a greenish-yellow gas is released and a bluish-green solution is formed.

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

Therefore, we have written the balanced equation of the reaction taking place between dilute HCl and copper oxide powder.
