Which one of the following alkali metals gives hydrated salts?
  1. Cs
  2. Li
  3. K
  4. Na

A
Na
B
K
C
Li
D
Cs
Solution
Verified by Toppr

Among alkali metal ions, Li+ is the smallest which has the highest charge density. Therefore, it has the maximum degree of hydration than any other alkali metal cation.

Q4
The solubility of alkali metal salts in water is due to the fact that the cations get hydrated by water molecules. The degree of hydration depends upon the size of the cation. If the trend of relative ionic radii is Cs+>Rb+>K+>Na+>Li+.
