On the basis of the general solubility rules given in Table 4.1, predict which of the following substances are likely to be soluble in water.
a. aluminum nitrate
b. magnesium chloride
c. rubidium sulfate
d. nickel(II) hydroxide
e. lead(II) sulfide
f. magnesium hydroxide
g. iron(III) phosphate
In each case, explain the reasons why some elements are more soluble than others in water.
