Question

36.H2SO4 acts as a strong oxidising agent. In which of the reaction, is it not acting as an oxidising agent? *

1 point

(a) C + 2H2SO4 → CO2 + 2SO2 + 2H2O

(b) CaF2 + 2H2SO4 → CaSO4 + 2HF

(c) S + 2H2SO4 → 3SO2 + H2O

(d) Cu + 2H2SO4 → CuSO4 + SO2 + 2H2O

​

Answer 1

Answer:

option B is correct

Explanation:

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

Answer 2

Answer:

b) $H_2SO_4$ acts as a strong oxidising agent.

$CaF_2 + 2H_2SO_4$ → $CaSO4_ + 2HF$

In this reaction, is it not acting as an oxidising agent.

Explanation:

Hot conc. $H_2SO_4$ acts as moderately strong oxidising agent. It oxidizes both metals and non-metals. Which of the following elements is oxidized by cone.

$C + 2H_2SO_4$ ⇒ $CO_2 +2SO_2 +2H_2O$

Carbon (C) is the elements  oxidized by conc. $H_2SO_4$  to give  two gaseous products which are $CO_2$  and $SO_2$.
