Read the following redox reaction and determine which reactant is reduced and which is oxidized.
f2 + zn --> znf2
which is reduced & which is oxidized? !

Answer : reactant is reduced and reactant is oxidized.

Explanation :

Redox reaction : It is a type of reaction in which an oxidation and reduction reaction takes palace simultaneously.

Oxidation : The loss of electrons or increase in the oxidation number is an oxidation.

Reduction : The gain of electrons or decrease in the oxidation number is a reduction.

The given balanced redox reaction is,

The oxidation number of = 0

The oxidation number of = 0

The oxidation number of Zn in

x + 2(-1) = 0

x = +2

The oxidation number of in = -1

That means is reduced due to decrease in the oxidation number from 0 to (-1) and 'Zn' is oxidized  due to increase in the oxidation number from 0 to (+2).

Therefore, reactant is reduced and reactant is oxidized.
