Quizplus · Accepted Answer

The name of the compound follows the format of “metal ion + polyatomic ion.” The polyatomic ion present here is sulfate (SO4)2-, and the metal ion is aluminum (Al)3+. Since there are two sulfate ions present, we use the prefix “di-” to indicate this, resulting in the name “dialuminum sulfate.” Therefore, the correct choice is E, which is "aluminum sulfate."
