Cl2 + Ca(OH)2 = H2O + CaOCl2

chlorine + calcium hydroxide ⟶ water + CaOCl2

Balance the chemical equation algebraically: + ⟶ + CaOCl2 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 + c_2 ⟶ c_3 + c_4 CaOCl2 Set the number of atoms in the reactants equal to the number of atoms in the products for Cl, Ca, H and O: Cl: | 2 c_1 = 2 c_4 Ca: | c_2 = c_4 H: | 2 c_2 = 2 c_3 O: | 2 c_2 = c_3 + c_4 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_1 = 1 and solve the system of equations for the remaining coefficients: c_1 = 1 c_2 = 1 c_3 = 1 c_4 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | + ⟶ + CaOCl2
