Vedclass · Answer

(A) The ionic conductivity in an aqueous solution depends on the degree of hydration of the ions.Smaller cations have a higher charge density,leading to a higher degree of hydration,which increases their effective size and decreases their mobility.The order of hydration is: $Li^+ > Na^+ > K^+ > Rb^+$.Since higher hydration leads to lower ionic mobility,the order of ionic conductivity is: $Li^+ < Na^+ < K^+ < Rb^+$.
