Problem

Two formula units of Al2(SO4)3\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 Al3+\text{Al}^{3+} ions and 6 SO42−\text{SO}_4^{2-} ions, all separately solvated. b) 4 Al3+\text{Al}^{3+} ions and 6 SO42−\text{SO}_4^{2-} ions, all separately solvated. c) 2 Al3+\text{Al}^{3+} ions and 3 SO42−\text{SO}_4^{2-} ions, all separately solvated. d) 4 Al2+\text{Al}^{2+} ions and 6 SO42−\text{SO}_4^{2-} ions, all separately solvated.
