Question

why Li exist as a hydrate salt​

Answer 1

Answer:

Among alkali metal ions, Li(I) has smallest size due to which it can easily polarize water molecules. Li salts get bonded to water of crystallization. ... The other alkali metals being bigger in size cannot easily polarize water molecules. Hence, there salts do not get bonded to water of crystallization.

Answer 2

Answer:

Lithium is the smallest in size among the alkali metals. Hence, Li+ ion can polarize water molecules more easily than other alkali metals. As a result, water molecules get attached to lithium salts as water of crystallization. Hence, lithium salts such as trihydrated lithium chloride (LiCl).
