NEETChemistryRedox ReactionsMCQ+4 / −1
Hot concentrated sulphate acid is a moderately strong oxidizing agent. Which of the following reactions does not show oxidizing behaviour?
  1. A
    Cu + 2H2SO4 →\to→ CuSO4 + SO2 + 2H2O
  2. B
    S + 2H2SO4 →\to→ 3SO2 + 2H2O
  3. C
    C + 2H2SO4 →\to→ CO2 + 2SO2 + 2H2O
  4. D
    CaF2 + H2SO4 →\to→ CaSO4 + 2HF
View written solutionFree

Correct answer: D

CaF2 + H2SO4 →\to→ CaSO4 + 2HF

Here, the oxidation state of every atom remains the same so, it is not a redox reaction.
