Answer is:
Al3+ < Mg2+ < K+ < Cs+
Explanation:
Larger the size of cation, less it polarizes the anion based on Fajan′s Rule.
Answer is:
Al3+ < Mg2+ < Na+
Explanation:
Smaller size and more charge favours more hydration. So, hydration radius increases, hence ionic mobility in aqueous medium decreases.
