Answer:
Al2(SO4)3 + 3 Ca(OH)2 → 3CaSO4 + 2Al(OH)3
Explanation:
1 mole of aluminium sulfate on reaction with 3 moles of calcium hydroxide gives 3 moles of calcium sulfate and 2 moles of aluminium hydroxide.
Al2(SO4)3 + 3 Ca(OH)2 → 3CaSO4 + 2Al(OH)3
here we have 2 moles of aluminium hydroxide so that aluminium on both the side can balance.
