From what i know, here's a list about some efflorescence and deliquescent compound:
Efflorescence: CoCl2, Na2CO3, Na2SO4
Deliquescent: CaCl2, MgCl2, ZnCl2
Then what about the other hydrated compound such as CuSO4, MgSO4, (NH4)3PO4, etc? And can someone give me another example of efflorescence and deliquescent compounds?
