Which of the following has the maximum solubility in water?

A

`LiHCO_(3)`

B

`NaHCO_(3)`

C

`KHCO_(3)`

D

`RbHCO_(3)`

Text Solution

Verified by Experts

The correct Answer is:
D
All the carbonates and bicarbonates of alkali metals are soluble in water.their solubilities increase rapidly on descending the group because their lattice enthalpies decrease more rapidly than their hydration enthalpies on moving down the group the group.
