Which of the following carbonate salt is...

Which of the following carbonate salt is soluble due to high entropy change?

A

`K_(2)CO_(3)`

B

`Li_(2)CO_(3)`

C

`(NH_(4))_(2)CO_(3)`

D

`Na_(2)CO_(3)`

Text Solution

Verified by Experts

The correct Answer is:
C
`DeltaH_(sol)` of ammonium salts are found to be positive but they are highly soluble due to high positive entropy change it makes `DetlaG_(sol)` more negative according to equation `DeltaG_(sol)=DeltaH_(sol)-TDeltaS_(sol)`
