Arrange the following alkaline -earth-metal iodates in order of decreasing solubility in water:
Ba(IO3)2 Be(IO3)2 Ra(IO3)2 Mg(IO3)2
Ba(IO3)2 Be(IO3)2 Ra(IO3)2 Mg(IO3)2
-
group 2 iodates
the smaller the atom, the less soluble it is
Ra > Ba > Mg > Be
the smaller the atom, the less soluble it is
Ra > Ba > Mg > Be
