Answer 2

In this question we have to find out the formula of the compound formed between al3+ and so42-

Here the charge of the aluminum ion is positive three(+3), and the charge of the sulfate polyatomic ion is negative two(-2). We have to find the appropriate number of each charge that will make their sum equal to zero.

Let's multiply the sulfate ion by three and the aluminum ion by two. That means here we need three sulfate ions and two aluminum ions to make a neutral ionic compound, the sum of the negative charges being 6 and the sum of the positive charges being 6 as well. Thus, the chemical formula of the neutral ionic compound made from a combination of aluminum ions and sulfate ions is   Al2(so4)3
