Question

When sodium peroxide is treated with $C{O}_2$, it will give:

• A. $N{a}_{2}C{O}_3$
• B. $NaOH$
• C. $Na$
• D. $C{O}_2$

Answer 1

The correct option is A $N{a}_{2}C{O}_3$

Sodium peroxide is used as an oxidising agent. When treated with $C{O}_2$, it gives sodium carbonate and oxygen.
$2N{a}_2{O}_2+2C{O}_2\to 2N{a}_{2}C{O}_3+O_2$
