hygroscopic and deliquescent salts?

Question

please group these salts into hygroscopic and deliquescent salts:
CaCl
NaCl
FeCl
H2SO4
KOH
NaOH

Answer 1

Hygroscopic salts are those which absorb water molecules from the atmosphere. From your list, you mean calcium chloride right? CaCl2 is hygroscopic, but so much to the point that it becomes deliquescent, which means that it absorbs a large enough amount of water that it will dissolve in the water taken in. NaOH is another example of this. If you left sodium hydroxide pellets out in the open, it would become a concentrated solution in a short amount of time. H2SO4 is an example of a hygroscopic salt. I'm not too sure about NaCl, but I don't believe that it is either. The salt in your salt shaker doesn't absorb any liquid, but I can't say for sure. Iron (III) chloride FeCl3, and KOH are both hygroscopic and deliquescent. Basically, anything that is deliquescent is also hygroscopic.

Hope this helps! Sorry if I made any mistakes

Answer 2

Hygroscopic Salts

Answer 3

I agree with Stephanie. She’s given you a definitive answer on everything, but Table salt, its hydroscopic. In fact give enough moisture and time it will crust over.
