QNEET-2017-Ch-930: NEET 2017 Chemistry - Class 11 NEET-2017-Ch-930 Solution: Ionic mobility of which of the following alkali metal ions is…
Ionic mobility of which of the following alkali metal ions is lowest when aqueous solution of their salts are put under an electric field? K Rb Li Na
Multiple Choice Options
- A K
- B Rb
- C Li
- D Na
Step-by-Step Verified Solution
Li + being smallest, has maximum charge
density.
So, Li + is most heavily hydrated among all alkali
metal ions. Effective size of Li + in aqueous
solution is therefore, largest. So, moves slowest
under electric field.
