Vedclass · Answer

(D) The conductivity of ions in an aqueous solution depends on their mobility. $Li^{+}$ has the smallest ionic size among alkali metals,which leads to a very high charge density. Due to this high charge density,$Li^{+}$ ions get highly hydrated in water,forming a large hydrated ion complex. This large size reduces the mobility of the ion in the solution,thereby decreasing its electrical conductivity.

Among alkali metal salts,lithium salts are the least conducting in their aqueous solutions. This is due to:
