Question

a) Identify substance getting oxidized and the one getting reduced
b) Oxidising and reducing agent in the following reactions.

1. Ca + Cl2 —> CaCl2
2. MnO2 + Al —> Mn + Al2O3
3. Fe2O3 + CO—> Fe + CO2
4. Fe+ S —>FeS
5. Zn(s)+CuSO4—>ZnSO4 + Cu(s)​

Answer 1

Answer:

can you ask today is about oxidation and reduction reaction

Answer 2

Answer:

substance oxidised Cl2

substance reduced Ca

Explanation:

1) substance oxidised Cl2 (loss of electrons from Cl- ions)

substance reduced : Ca (gain of electrons from Ca+2 ions)

oxidising agent : Ca

reducing agent : Cl2

2) substance oxidised :Al

substance reduced : MnO2

oxidising agent : MnO2

reducing agent : Al

3) substance oxidised : CO

substance reduced : Fe2O3

oxidising agent : Fe2O3

reducing agent : CO

4)

substance oxidised : S

substance reduced : Fe

oxidising agent : Fe

reducing agent : S

5) substance oxidised :Zn

substance reduced : Cu+2 ion

oxidising agent : Cu+2 ion

reducing agent : Zn
