Explanation / Answer

1) Nitrates of alkali and alkaline earth metals are all soluble in water. Their solubilities inreases from top to bottom in the group.

Hence,

solubility of alkaline earth nitrates increases from top to bottom i.e. increases from Be to Ba.

Therefore,

   order of solubility is     Ba(NO3)2 > Sr(NO3)2 > Ca(NO3)2 > Mg(NO3)2

Rank :     Ba(NO3)2 > Sr(NO3)2 > Ca(NO3)2 > Mg(NO3)2

              most soluble                                         least soluble
