Ncert Exercises & Solutions

The formula of soda ash is

1. ${Na}_{2} {CO}_{3} \cdot 10 H_{2} O$

2. ${Na}_{2} {CO}_{3} \cdot 2 H_{2} O$

3. ${Na}_{2} {CO}_{3} \cdot H_{2} O$

4. ${Na}_{2} {CO}_{3}$

Hint: Soda ash is anhydrous sodium carbonate

On heating washing soda, it loses its water of crystallisation. Above 373 K, it becomes a completely anhydrous white powder called soda ash.

\underset{Washing soda}{{Na}_{2} {CO}_{3} \cdot 10 H_{2} O} \overset{> 373 K}{\to} \underset{Soda ash}{{Na}_{2} {CO}_{3}} + 10 H_{2} O
