Na2CO3 is anhydrous salt. Whereas Na2CO3.10H2O is hydrated salt that contains 10 molecules of water of crystallization.
washing soda contain 10 water of crystallization.
when it exposed to air get lost the water of crystallization.
that is 10 particle of H2O
this process of losing of water of crystallization is known as effervescent.
hope it helps!!!!!
for more detail consult to me.
