1.	Ionic mobility of which of the following alkali metal ions is lowest when aqueous solution of their salts are put under an electric field ?
Answer» K RB LI Na Solution :`Li^(+)` being the smallest alkali metal cation is most HIGHLY hydrated . As a result , the mass of the hydrated species is the highest and its mobility in the electric field is the lowest .
