The order solubility in water of alkaline earth metal sulphates down the group is $$Be > Mg > Ca > Sr > Ba.$$ This is due to increases in
A.
ionization energy
B.
melting point
C.
coordination number
D.
All of these
Answer :
coordination number
Solution :
In crystalline sulphates, the coordination number of the ions increases from $$Be$$ to $$Ba$$ and so also the lattice energy hence solubility in $${H_2}O$$ decreases.
