Question

Balance the following equation:

Al_(s) + KOH_(aq) + H₂SO_4(aq)+ H₂O_(l) ---> KAl(SO₄)₂ * 12 H₂O_(s) + H₂_(g)

Answer 1

Answer #1

During balancing a chemical equation, it is important to consider the law of conservation of mass which states that the mass of the reactants must be equal to the mass of the products.
In order to make masses equal, the number of atoms of each element in the reactant side must be equal to the number of atoms of those same elements in the products side. The balanced reaction is given below-
2Al(s) + 2KOH(aq.) +4 H2SO4(aq.) + 22H20(l) - - - > 2KAl(SO4)2*12H20(s) + 3H2(g).
