A Redox (reduction - Oxidation) reaction is also called as a disproportionation reaction. It involves oxidizing agents or reducing agents, according to the type of reaction.
To calculate the equivalent weight of a substance in a redox reaction, we have to first calculate the molecular weight of the substance, which can either be a reducing agent, also known as the reductant or an oxidizing agent, also known as the oxidant.
The equivalent weight can be calculated as the molecular weight (MW) of the substance divided by the number of electrons that have been gained or lost per molecule of the reactant (substance). It can also be considered as the ratio of MW to the change in the oxidation number of per mole.

Eq. wt. of Oxidant = Molecular weight / No. of moles that is gained by 1 mole of the substance
It can also be, Eq.wt of oxidizing agent = Mol. wt / Change in Oxidation number per mole.
Eq. wt. of Reductant. = Molecular weight / No. of moles that is lost by 1 mole of the substance
Like for the oxidant, it can also be, Eq.wt of oxidizing agent = Mol. wt / Change in Oxidation number per mole.
