Chemistry-Balancing Redox Reactions
NEET Chemistry Balancing Redox Reactions MCQ Question
Type: MCQ-diagram based-Easy-Class 11
In the diagram depicting the balancing of the redox reaction between iodide ions and permanganate ions in basic medium, which step involves the multiplication of the reduction half-reaction by a factor to equalize the number of electrons transferred?
A
Multiplication of oxidation half-reaction by 3
B
Multiplication of reduction half-reaction by 2
C
Addition of half-reactions to cancel electrons
D
Balancing charges in half-reactions
Correct Answer
Option B
Detailed Explanation
In step 5, the reduction half-reaction is multiplied by 2 to equalize the electrons with the oxidation half-reaction that is multiplied by 3, allowing electron cancellation in the next step.
