Question
Arrange in the decreasing order of ionic mobility of ion :-Be2+(aq) > Mg2+ (aq) > Ca2+(aq) > Sr2+ (aq) > Ba2+ (aq)Sr2+ (aq) > Ba2+ (aq) > Ca2+(aq) > Mg2+ (aq) > Be2+ (aq)Ba2+ (aq) > Sr2+ (aq) > Ca2+ (aq) > Mg2+ (aq) > Be2+ (aq)Mg2+(aq) > Ca2+ (aq) > Be2+(aq) > Sr2+ (aq) > Ba2+ (aq)
Solution
Ionic mobility is influenced by the size of the ion and its charge. Smaller ions and ions with higher charges tend to have lower mobility because they interact more strongly with the solvent, which slows them down.
In the series Be2+, Mg2+, Ca2+, Sr2+, and Ba2+, all the ions have the same charge (+2), but their sizes increase from Be2+ to Ba2+. Therefore, the ionic mobility decreases from Be2+ to Ba2+.
So, the correct order of decreasing ionic mobility is:
Be2+(aq) > Mg2+ (aq) > Ca2+(aq) > Sr2+ (aq) > Ba2+ (aq)
Therefore, the correct answer is "Be2+(aq) > Mg2+ (aq) > Ca2+(aq) > Sr2+ (aq) > Ba2+ (aq)".
