Question

what is the reaction called when oxidation and reduction takes place simultaneously ? explain with one example.

Answer 1

Answer:

oxidation+reduction=redox reaction

exp: c+o2=co2

Explanation:

To understand the equation u need to know how to calculate oxidation state. Here, the value of c and o2 is 0 as it is formed with same element and the value of c in co2 is +4 and value of o in co2 is -2 so here, c is oxidized and o is reduced.

If u find this answer helpful then pls mark this question as brainlist answer.

Answer 2

Answer:

Explanation:

(i) When oxidation and reduction take place

simultaneously in a given reaction it is termed as

Redox reaction.

(ii) During oxidation a reactant combines with

oxygen or loses hydrogen and during reduction

it gains hydrogen or loses oxygen.

(iii) Example of Redox reaction:

2H2

S + SO2 → 3S + 2H2

O

oxidation (O2

added)

reduction (O2

lost)

(iv) In the above reaction, SO2

is reduced and H2

S is

oxidised.
