Question

In which of the following reaction $H_2O_2$ is a reducing agent ?

• A. $2FeCl_2+2HCl+H_2O_2\to2FeCl_3 + 2H_2O$
• B. $Cl_2 + H_2O_2 \to 2HCl + O_2$
• C. $2HI + H_2O_2\to2H_2O + I_2$
• D. $H_2SO_3 + H_2O_2\to H_2SO_4 + H_2O$

Answer 1

Answer: (B)

$Cl_2 + H_2O_2 \to 2HCl + O_2$

Answer 2

In (B) $H_2O_ 2 (O.N. of O = -1)$ is getting oxidised to $O_ 2(O.N. of 0 = 0)$ and thus acts as a reducing age
