Which one of the following alkaline earth metal ions has the highest ionic mobility in its aqueous s — Chemical Bonding Chemistry Question
Question
Which one of the following alkaline earth metal ions has the highest ionic mobility in its aqueous solution? 2+ 2+ 2+ 2+ 2+ 2+ 2+ 2+ 2+ (A) Be (B) Mg (C) Ca (D) Sr
Answer: A) BE
💡 Solution & Explanation
Smaller the size of ion greater is it’s hydration & greater is it’s hydrated radii & smaller is ionic mobility. So order of ionic mobility: Be < Mg < Ca < Sr < Ba
