NEET Chemistry Balancing Redox Reactions MCQ Question
In balancing redox reactions, how do you equalize the number of electrons in the half-reactions?
By multiplying the oxidation and reduction half-reactions by appropriate coefficients.
By adding the half-reactions directly without adjustments.
By balancing only the mass of atoms in the half-reactions.
By changing the oxidation states of the reactants.
Correct Answer
Detailed Explanation
To equalize the number of electrons in redox reactions, the oxidation half-reaction is multiplied by 3 and the reduction half-reaction by 2, as shown in the example from the NCERT context.
