Input interpretation
chlorine + potassium hydroxide + Cr(OH)3 ⟶ water + potassium chloride + potassium chromate
Balanced equation
Balance the chemical equation algebraically: + + Cr(OH)3 ⟶ + + Add stoichiometric coefficients, c_i, to the reactants and products: c_1 + c_2 + c_3 Cr(OH)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 Cl, H, K, O and Cr: Cl: | 2 c_1 = c_5 H: | c_2 + 3 c_3 = 2 c_4 K: | c_2 = c_5 + 2 c_6 O: | c_2 + 3 c_3 = c_4 + 4 c_6 Cr: | c_3 = c_6 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_3 = 1 and solve the system of equations for the remaining coefficients: c_1 = 3/2 c_2 = 5 c_3 = 1 c_4 = 4 c_5 = 3 c_6 = 1 Multiply by the least common denominator, 2, to eliminate fractional coefficients: c_1 = 3 c_2 = 10 c_3 = 2 c_4 = 8 c_5 = 6 c_6 = 2 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | 3 + 10 + 2 Cr(OH)3 ⟶ 8 + 6 + 2
