Question

D) State whether the following is oxidation or reduction reaction and also mention the oxidizing and reducing Agent where required only.
i. CO2 + H2 → CO + H2O
ii. CuO + H₂ → Cu + H2O
iii. Zn → Zn2+ + 2e −
iv. CH3CH2OH → CH3CHO
v. Cu2+ + Mg → Cu + Mg2+ SE​

An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two species. In redox reaction the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron.

In the reaction : CuO+H

2

⟶Cu+H

2

O

n the reaction H

is oxidized since it has lost electrons and Cu is reduced since it has gained electrons.

Answer 2

D) State whether the following is oxidation or reduction reaction and also mention the oxidizing and reducing Agent where required only.

i. CO2 + H2 → CO + H2O

ii. CuO + H₂ → Cu + H2O

iii. Zn → Zn2+ + 2e −

iv. CH3CH2OH → CH3CHO

v. Cu2+ + Mg → Cu + Mg2+ SE

that's bîo
