The correct formula for the ionic compound containing Al³⁺ and PO would be _____. A)Al₃(PO₄)₃ B)AlPO₄ C)Al₃(PO₄)₂ D)Al₂(PO₄)₃

Question

Quizplus · Accepted Answer

The formula for an ionic compound must indicate the cation (positive ion) first and the anion (negative ion) second. In this case, the cation is aluminum (Al) and the anion is a combination of sulfide (S2-) and phosphide (P3-) ions, as well as sulfate (SO42-) and phosphate (PO43-) ions.

The correct way to indicate this is by using parentheses and subscripts to specify the number of each type of ion present in the formula unit. Using this method, the formula for the compound would be Al(PO4)(S)(P). However, since the sulfate ion is not mentioned in the problem, we can ignore it and just list the remaining ions.

Therefore, the correct formula for the compound would be Al(PO4)(S)(P), which is option B.
