AIIMS 2018 Chemistry Oxidation and Reduction MCQ Question
Blue colour disappears in which solution by passing
Correct Answer
Detailed Explanation
In the reaction between iodine (I₂) and sulfur dioxide (SO₂), iodine is reduced to iodide ions (I⁻), while sulfur dioxide is oxidized to sulfate ions (SO₄²⁻). This transfer of electrons characterizes a reduction-oxidation (redox) reaction, making option B the correct choice. Option A (oxidation) is incorrect because it only describes half of the process; option C (displacement) does not apply as there is no element being displaced; and option D (neutralization) is irrelevant since no acid-base reaction is occurring.
