AIIMS 2019 Chemistry Oxidizing Agents MCQ Question
Which of the following can react with
Correct Answer
Detailed Explanation
In the reaction between K₂Cr₂O₇ and SO₃²⁻, potassium dichromate (K₂Cr₂O₇) acts as a strong oxidizing agent, facilitating the oxidation of sulfite ions (SO₃²⁻) to sulfate ions (SO₄²⁻), while being reduced to chromium ions (Cr³⁺). This redox process is characterized by the transfer of electrons from the sulfite to the dichromate, highlighting the fundamental principles of oxidation and reduction in chemical reactions. Since the other options are not provided, they cannot be evaluated; however, it is essential to recognize that the oxidation state changes and electron transfer are key concepts in understanding redox chemistry.
