\text{Al}_2(\text{SO}_4)_3

completely dissolve in a beaker of water. Which set of ions would correctly appear in a particulate diagram of the resulting solution? (a) 2

\text{Al}^{3+}

ions and 6

\text{SO}_4^{2-}

ions, all separately solvated. (b) 4

\text{Al}^{3+}

ions and 6

\text{SO}_4^{2-}

ions, all separately solvated. (c) 2

\text{Al}^{3+}

ions and 3

\text{SO}_4^{2-}

ions, all separately solvated. (d) 4

\text{Al}^{2+}

ions and 6

\text{SO}_4^{2-}

ions, all separately solvated.
