Sodium on heating with moist air produces

Question

Sodium on heating with moist air produces (A) NaO (B) NaO2 (C) Na2O (D) Na2CO3

Tardigrade Admin · Accepted Answer

When sodium is heated with moist air, the ultimate product obtained is

N a_{2} C O_{3}

. In moist air, a layer of sodium oxide, hydroxide and carbonate is formed on its surface due to which, it loses its lustre.
The complete reaction sequence is as follows:

4 N a + O_{2} \to 2 N a_{2} O 2 H_{2} O 4 N a O H 2 C O_{2} 2 N a_{2} C O_{3} + 2 H_{2} O
