Detailed Solution

Ether can extract LiCl from the aqueous solution of a mixture of LiCl , NaCl and KCl mixed and shaked well, the water is polar solvant and hence polar compounds KCl, NaCl moves into water, where as the non-polar compound LiCl moves into non polar ether solvent Principle involved here is like dissolves like polar compounds soluble in polar solvents [H2O] where as non polar compound soluble in non polar solvents [Ether] As the size of alkali metal ion increases nuclear charge density decreases hence attraction of water molecules decreases therefore degree of hydraction decreases Statement -I & statement - II are correct
