The lowest common multiple of 3 and 2 is 6, so we will need six positive and six negative charges: two Al3+ and three SO 4 2– ions, and the formula for aluminum sulfate is Al 2(SO 4) 3. Then, in a formula unit of Al 2(SO 4) 3 there are two aluminum ions and three sulfate ions; or two aluminum, three sulfur, and twelve oxygen atoms.
