When crystals of potassium bromide are heated with MnO₂ and conc. H₂SO₄ then
Options:(select one or more)
Answer:
A, B, C
Solution:
2KBr + MnO₂ + 2H₂SO₄ → K₂SO₄ + MnSO₄ + Br₂ + 2H₂O : Br⁻ (−1) is oxidised to Br₂ (0) while MnO₂ (Mn +4 → +2) is the oxidising agent, and 2 mol KBr give 1 mol Br₂. No SO₂ is evolved in this reaction, so (D) is false.
