Which step is irrelevant with respect to balancing of redox equations by oxidation number method?

آکسیڈیشن نمبر طریقہ کے ذریعہ ریڈوکس مساوات کے توازن کے سلسلے میں کون سا مرحلہ غیر متعلقہ ہے؟

Identify the element undergoing a change in oxidation number

Equalize the number of electrons lost and gained

Split the reaction into two half reactions

Assign oxidation number to all the atoms involved in the equation

The irrelevant step in balancing redox equations by the oxidation number method is "Split the reaction into two half reactions."

This step is part of the ion-electron method, not the oxidation number method.

It focuses on changes in oxidation states.
