QNEET-2016-Ch-1119: NEET 2016 Chemistry - Class 11 NEET-2016-Ch-1119 Solution: Hot concentrated sulphate acid is a moderately strong oxidizing …

Hot concentrated sulphate acid is a moderately strong oxidizing agent. Which of the following reactions does not show oxidizing behaviour? Cu+2H2SO4→CuSO4+SO2+2H2OCu + 2H_2SO_4 \rightarrow CuSO_4 + SO_2 + 2H_2O S+2H2SO4→3SO2+2H2OS + 2H_2SO_4 \rightarrow 3SO_2 + 2H_2O C+2H2SO4→CO2+2SO2+2H2OC + 2H_2SO_4 \rightarrow CO_2 + 2SO_2 + 2H_2O CaF2+H2SO4→CaSO4+2HFCaF_2 + H_2SO_4 \rightarrow CaSO_4 + 2HF

Multiple Choice Options

  • A Cu + 2H 2 SO 4 →\to _ CuSO 4 + SO 2 + 2H 2 O
  • B S + 2H 2 SO 4 →\to _ 3SO 2 + 2H 2 O
  • C C + 2H 2 SO 4 →\to _ CO 2 + 2SO 2 + 2H 2 O
  • D CaF 2 + H 2 SO 4 →\to _ CaSO 4 + 2HF

Step-by-Step Verified Solution

CaF 2 + H 2 SO 4 _ CaSO 4 + 2HF Here, the oxidation state of every atom remains the same so, it is not a redox reaction.
