Why are lithium salts commonly hydrated ...

Why are lithium salts commonly hydrated and those of the other alkali ions usually anhydrous?

Text Solution

Verified by Experts

Because of high charge density among alkali metals, `Li^(o+)` can polarise water molecules more easily than the other alkali metal ions and hence get attached to lithium salts as water of crystallisation. For example, lithium chloride crystallises as `LiCl.2H_(2)O`.

Why are lithium salts commonly hydrated while those of other alkali metal ions ar usually anhydrous?

Assertion: Lithium salts are mostly hydrated. Reason: The hydration enthalpies of alkalie metal ions decrease with increase in ionic sizes.

Statement-1:The lithium ion itself, and also its compounds, are more heavily hydrated than those of the rest of the group members. Statement-2:The Li^+ is smallest among alkali metals and polarise water molecules more easily than the other alkali metal ions.

(a) Why are some salts called hydrated salts ? (b) Give two examples of white coloured hydrated slts alongwith their chemical formula.

Statement 1: Lithium form hydrated chlorides but other alkali metals do not form hydrated chlorides Statement 2: Lithium has more polarising power than other
