which one of the following has maximum value of cationic/anionic ratio Ecc
Dear student
30.Ans: C
Sol:-
Atomic size of K+> Ca+2>Na+>Mg+2 that of Cl->F-
So, Mg+2/Cl- i.e option C is correct.
31. Ans: A
Sol:-
The hydroxides of 1st group are strong bases and HCl is a strong acid, therefore, the chlorides of 1st group elements are salts of strong acids and strong bases. As such they do not undergo hydrolysis thereby yielding neutral solutions.
