Question

iii) Observe the following reaction carefully and answer the questions below:
8 and R
CuO+H2 Cu + H2O
(a) Name the reductant in above reaction.
(b) Name the oxidant in above reaction.
(c) Give one more example of such reaction.​

Answer 1

Answer:

(a) reductant is Cuo

(b)oxidant is H2O

(C) Such eg is:- Fe2O3 + 2Al ----Al2O3+ 2Fe**

Explanation:

(a) As Cuo is reducing from *Cuo* to Cu

(b) As H2 is oxidant by adding oxygen in H2 to form H2O

(c) this reaction is also showing reductant and oxidant

Answer 2

The given reaction is-

$CuO+H_2\rightarrow Cu+H_2O$.

• The species which get reduced is called an oxidant. Here CuO is reduced to Cu. So, CuO is an oxidant.
• The species which gets oxidised is called a reductant. Here hydrogen gets oxidised to water. So, it is a reductant.
• Such a reaction is called a redox reaction.
• One more example of a redox reaction is-
• $Fe_2O_3+2Al\rightarrow Al_2O_3+2Fe$.
