Input interpretation
potassium hydroxide + potassium permanganate + sodium iodide ⟶ sodium hydroxide + iodine + potassium manganate
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, K, O, Mn, I and Na: H: | c_1 = c_4 K: | c_1 + c_2 = 2 c_6 O: | c_1 + 4 c_2 = c_4 + 4 c_6 Mn: | c_2 = c_6 I: | c_3 = 2 c_5 Na: | 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_5 = 1 and solve the system of equations for the remaining coefficients: c_1 = 2 c_2 = 2 c_3 = 2 c_4 = 2 c_5 = 1 c_6 = 2 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | 2 + 2 + 2 ⟶ 2 + + 2
