Select the correct balanced equation for the reaction Al2(SO4)3 + BaCl2 → AlCl3 + BaSO4 .
Al2(SO4)3 + 3BaCl2 → 2AlCl3 + 3BaSO4
The correct answer is Option 4 i.e. Al2(SO4)3 + 3BaCl2 → 2AlCl3 + 3BaSO4.
The correct balanced equation for the reaction:
Al2(SO4)3 + BaCl2 → AlCl3 + BaSO4
is:
Al2(SO4)3 + 3BaCl2 → 2AlCl3 + 3BaSO4
Explanation:
-
Aluminum (Al): There are 2 aluminum atoms on the left side (from Al2(SO4)3), so we need 2 AlCl3 on the right side to balance the aluminum.
-
Sulfate (SO₄²⁻): There are 3 sulfate ions on the left (from Al2(SO4)3), so we need 3 BaSO4 molecules on the right.
-
Barium (Ba): On the right side, there are 3 barium ions from 3BaSO4, so we need 3 BaCl2 on the left side.
-
Chlorine (Cl): 3 BaCl2molecules on the left give us 6 chlorine atoms, which balance with the 6 chlorine atoms in 2 AlCl3 molecules on the right.
