Question
Sodium peroxide ($Na_2O_2$) is widely used as an oxidizing agent and for purifying air in confined spaces like submarines. What are the products formed when it reacts with the carbon dioxide ($CO_2$) exhaled in such spaces?
Answer: A
💡 Solution & Explanation
Sodium peroxide reacts with $CO_2$ to form sodium carbonate and liberate oxygen gas. This reaction ($2Na_2O_2 + 2CO_2 \rightarrow 2Na_2CO_3 + O_2$) removes $CO_2$ and replenishes $O_2$, making it ideal for air purification in submarines.
