Balanced equation

Balance the chemical equation algebraically: NaOH + CrCl_3 ⟶ NaCl + Cr(OH)3 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 NaOH + c_2 CrCl_3 ⟶ c_3 NaCl + c_4 Cr(OH)3 Set the number of atoms in the reactants equal to the number of atoms in the products for H, Na, O, Cl and Cr: H: | c_1 = 3 c_4 Na: | c_1 = c_3 O: | c_1 = 3 c_4 Cl: | 3 c_2 = c_3 Cr: | c_2 = 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_2 = 1 and solve the system of equations for the remaining coefficients: c_1 = 3 c_2 = 1 c_3 = 3 c_4 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | 3 NaOH + CrCl_3 ⟶ 3 NaCl + Cr(OH)3
