Web19 mrt. 2024 · Now, we know that ionic mobility is related to the ease or speed with which an ion can move in a solution. We can add to this that highly solvated ions have a large number of solvent molecules around them and thus have less mobility. So, hydration enthalpy is inversely proportional to the ionic mobility as well. WebThe correct order of the mobility of the alkali metal ions in aqueous ... Ionic radii of alkali metals in water follows the order Li + > Na + > K + > Rb + > Cs + Thus in aqueous solution due to larger ionic radius Li + has lowest mobility and hence the correct order of ionic mobility is Li + < Na + < K + < Rb + Most Upvoted Answer
