Solution

The correct option is C
${N a}_{2} C O_{3}$

The constituent ions present in sodium carbonate are $N a^{+}$ and ${CO}_{3}_{3}^{2 -}$

Symbol: Na $C O_{3}$

Charge: +1 -2

To balance the charges, we cross multiply the valencies and get the chemical formula of sodium carbonate as ${N a}_{2} C O_{3}$ .
