• A. 5, 1, 6
• B. 1, 5, 6
• C. 6, 1, 5
• D. 5, 6, 1

Hint:

Balance redox reactions using half-reaction method.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Balance the redox reaction using half-reaction method.
Step 2: Detailed Explanation:
Balanced equation: $5\mathrm{I}^- + \mathrm{IO}_3^- + 6\mathrm{H}^+ \rightarrow 3\mathrm{I}_2 + 3\mathrm{H}_2\mathrm{O}$. Coefficients: 5, 1, 6.
Step 3: Final Answer:
The coefficients are 5, 1, 6.
