Crystalline sodium carbonate = Na₂CO₃·10H₂O
When exposed to air,
Na₂CO₃·10H₂O loses its water of crystallisation and becomes monohydrated Sodium Carbonate i.e. Na₂CO₃·H₂O+ 9H₂O.
Na₂CO₃·10H₂O ⇄ Na₂CO₃H₂O + 9H₂O
When exposed to air,
Na₂CO₃·10H₂O loses its water of crystallisation and becomes monohydrated Sodium Carbonate i.e. Na₂CO₃·H₂O+ 9H₂O.
Na₂CO₃·10H₂O ⇄ Na₂CO₃H₂O + 9H₂O

If we keep crystalline sodium carbonate exposed in the atmospheric air ,it becomes monohydrated sodium carbonate by losing it's molecular water.And the final product is wet and slimy.
Equation of this chemical reaction is :
Na2CO3·10H2O --> Na2CO3H2O + 9H2O
That's why we have preserve sodium bicarbonate in the airtight container.
