question_answer 1)

Comment on each of the following observations: (a) The mobilities of alkali metal ions in aqueous solutions are \[L{{i}^{+}}

Answer:

(a) The degree of hydration is more for smaller ions. Thus, the mass of the hydrated ions follows the following order. \[L{{i}^{+}}(aq)>N{{a}^{+}}(aq)>{{K}^{+}}(aq)>R{{b}^{+}}(aq)\] Therefore, the ionic mobility follows the following order: \[L{{i}^{+}}(aq)
