Balanced equation

Balance the chemical equation algebraically: H_2O + Al_2(SO_4)_3 ⟶ H_2SO_4 + Al(OH)_3 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 H_2O + c_2 Al_2(SO_4)_3 ⟶ c_3 H_2SO_4 + c_4 Al(OH)_3 Set the number of atoms in the reactants equal to the number of atoms in the products for H, O, Al and S: H: | 2 c_1 = 2 c_3 + 3 c_4 O: | c_1 + 12 c_2 = 4 c_3 + 3 c_4 Al: | 2 c_2 = c_4 S: | 3 c_2 = c_3 Since the coefficients are relative quantities and underdetermined, choose a coefficient to set arbitrarily. To keep the coefficients small, the arbitrary value is ordinarily one. For instance, set c_2 = 1 and solve the system of equations for the remaining coefficients: c_1 = 6 c_2 = 1 c_3 = 3 c_4 = 2 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | 6 H_2O + Al_2(SO_4)_3 ⟶ 3 H_2SO_4 + 2 Al(OH)_3
