Question

In the reaction, ${H_2O_2 + Na_2 CO_3 -> Na_2O_2 + CO_2 + H_2O}$ the substance undergoing oxidation is

• A. $\ce{H_2 O_2}$
• B. none
• C. $\ce{Na_2CO_3}$
• D. $\ce{Na_2O_2}$

Answer 1

Answer: (B)

none

Answer 2

$\overset{\text{+1 }}{ {H_2 }}$ {\overset{\text{-1 }}{ {O_2 }}$+$Na_2$$\overset{\text{+4 }}{ {C}}$$\overset{\text{ -2 }}{ {O_3}}$->$Na_2$$\overset{\text{-1 }}{ { O_2 }}$+$\overset{\text{+4}}{ {C}}$O_2 +$\overset{\text{+1}}{ {H_2}}$$\overset{\text{-2}}{ {O}} } None of the element changes its O.N. and hence option (b) is correct.
