H 2 O 2 acts as a reducing agent in

Question

H 2 O 2 acts as a reducing agent in (A) Na 2 S +4 H 2 O 2 arrow Na 2 SO 4+4 H 2 O (B) Mn 2++2 H 2 O 2 arrow MnO 2+2 H 2 O (C) 2 Fe 2++2 H ++ H 2 O 2 arrow 2 Fe 3++2 H 2 O (D) 2 NaOCl + H 2 O 2 arrow 2 NaCl + H 2 O + O 2

Correct answer is (d) 2 NaOCl + H 2 O 2 arrow 2 NaCl + H 2 O + O 2

Q. $H_{2} O_{2}$ acts as a reducing agent in

$N a_{2} S + 4 H_{2} O_{2} \to N a_{2} S O_{4} + 4 H_{2} O$

$M n^{2 +} + 2 H_{2} O_{2} \to M n O_{2} + 2 H_{2} O$

$2 F e^{2 +} + 2 H^{+} + H_{2} O_{2} \to 2 F e^{3 +} + 2 H_{2} O$

$2 N a OCl + H_{2} O_{2} \to 2 N a Cl + H_{2} O + O_{2}$

Correct answer is (d) $2 N a OCl + H_{2} O_{2} \to 2 N a Cl + H_{2} O + O_{2}$
