Below what relative humidity does Z·2H2O lose water spontaneously at this temperature?
Options:
Answer:
C
Solution:
For the Z hydrate, pH2O,eq=√(2.50×10-5)=0.005 atm. Dehydration is favoured when the atmospheric water pressure is smaller than 0.005 atm.
The limiting relative humidity is 100(0.005/0.050)=10%.
The hydrate therefore loses water below 10% relative humidity.
This is option (c).
