Question

In the given equation
CuO + H2 = Cu +H2O
Identify : what is oxidised, reduced, reducing agent, oxidising agent
​

Answer 1

Answer:

CuO(+2) is reduced to Cu(0) and H2(0) is oxidised to H2O(+1) .

CuO is an oxidising agent while H2 is reducing agent.

Explanation:

Increase in oxidation state is the Oxidation while decrease in oxidation state is reduction.

The substance which helps in oxidation of other and itself undergoes reduction is called oxidising agent while the substance which helps in reduction of other and itself undergoes oxidation is called reducing agent.

Answer 2

Answer:

CuO(+2) is reduced to Cu(0) and H2(0) is oxidised to H2O(+1) .

CuO is an oxidising agent while H2 is reducing agent.

Explanation:

Increase in oxidation state is the Oxidation while decrease in oxidation state is reduction.

The substance which helps in oxidation of other and itself undergoes reduction is called oxidising agent while the substance which helps in reduction of other and itself undergoes oxidation is called reducing agent.
