K+ will have the highest mobility in aqueous medium as it has small size.


In this case Li+ is an exception as it has high attraction towards water. that combines with it and make Li+ bulky thus reducing its mobility in aqueous medium.


Hope this answer satisfies your requirements.

imrahul02: galat hai
imrahul02: ap logo ko ans hi nhi pata to explain kya karenge
mimansha2712: is Rb the answer
imrahul02: howww
mimansha2712: the mobility of ions is inversely proportional to the size of their hydrated ions. Lithium is surrounded by 6 water molecules hence have low mobility whereas mobility increases down the group. Maybe i missed that thing while giving answer.
mimansha2712: is it right now
imrahul02: coollll
imrahul02: yes appears right
mimansha2712: alst thanks anyway it cleared my concepta too
imrahul02: ok
