Input interpretation
copper(II) sulfate + sodium iodide ⟶ sodium sulfate + CuI2
Balanced equation
Balance the chemical equation algebraically: + ⟶ + CuI2 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 + c_2 ⟶ c_3 + c_4 CuI2 Set the number of atoms in the reactants equal to the number of atoms in the products for Cu, O, S, I and Na: Cu: | c_1 = c_4 O: | 4 c_1 = 4 c_3 S: | c_1 = c_3 I: | c_2 = 2 c_4 Na: | c_2 = 2 c_3 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 = 2 c_3 = 1 c_4 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | + 2 ⟶ + CuI2
