Question

Which of the following salts has no water of crystallization?
1 point
POP
Washing soda
Baking soda
Gypsum
​

Answer 1

Answer:

BAKING SODA HAS NO WATER OF CRYSTALLISATION.

BECAUSE ITS FORMULA IS

NaHCO3.

but ,

pop has 1/2 water of CRYSTALLISATION.

as it's formula is CaSO4.1/2 H2O

means two molecules of CaSO4

share one molecule of water.

and, washing soda = Na2CO3.10H2O.

so, it contains 10 water of CRYSTALLISATION.

GYPSUM= CaSO4.2H2O

so, it contains 2 water of CRYSTALLISATION.....ok
