Al2(SO4)3
just switch the charges of aluminum and sulfate :)
Al has a charge of 3+ and sulfate has a charge of 2-
switch them and put parenthasese around the sulfate ion since it's polyatomic, and the 4 stays there since it's part of sulfate.
and then just switch the charges
hope i helped =)
OK PLZ DON'T FORGOT TO MARK AS BRAIN LIST IF I M CORRECT....
