AIPMT PRELIMS 2006 Chemistry Ionic Mobility MCQ Question
The correct order of the mobility of the alkali metal ions in aqueous solution is :
Li⁺ > Na⁺ > K⁺ > Rb⁺
Na⁺ > K⁺ > Rb⁺ > Li⁺
Na⁺ > K⁺ > Li⁺ > Rb⁺
Li⁺ > K⁺ > Na⁺ > Rb⁺
Correct Answer
Detailed Explanation
In aqueous solution, the mobility of alkali metal ions is influenced by their hydration. Li⁺, being the smallest, is most heavily hydrated, reducing its mobility compared to larger ions like Na⁺ and K⁺.
