Input interpretation
sulfuric acid + potassium dichromate + potassium sulfite ⟶ water + potassium sulfate + chromium sulfate
Balanced equation
Balance the chemical equation algebraically: + + ⟶ + + Add stoichiometric coefficients, c_i, to the reactants and products: c_1 + c_2 + c_3 ⟶ c_4 + c_5 + c_6 Set the number of atoms in the reactants equal to the number of atoms in the products for H, O, S, Cr and K: H: | 2 c_1 = 2 c_4 O: | 4 c_1 + 7 c_2 + 3 c_3 = c_4 + 4 c_5 + 12 c_6 S: | c_1 + c_3 = c_5 + 3 c_6 Cr: | 2 c_2 = 2 c_6 K: | 2 c_2 + 2 c_3 = 2 c_5 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 = 4 c_2 = 1 c_3 = 3 c_4 = 4 c_5 = 4 c_6 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | 4 + + 3 ⟶ 4 + 4 +
