    Balancing a redox reaction ....

    Use the half reaction method

    S2O3^2- + Cl2 --> HSO4^- + Cl- ............ start with the ions

    S2O3^2- + 5H2O --> 2HSO4^- + 8H+ + 8e- .... oxidation half-reaction

    4(Cl2 + 2e- --> 2Cl-) ................. .................... ... reduction half-reaction

    ------------------ --------------------- ----------------- -----------

    S2O3^2- + 4Cl2 + 5H2O --> 2HSO4^- + 8Cl- + 8H+ .... balanced net ionic eqn.

    Now, if you like, you can write a balanced "molecular" equation.

    Na2S2O3(aq) + 4Cl2(g) + 5H2O(l) --> 2NaHSO4(aq) + 8HCl(aq)

      Daniel, you copied electron1's answer, so both of you got it wrong. Just do your own work and don't copy and paste from another answer.

    Na2SO3 + Cl2 + H2O → NaHSO4 + HCl

    To balance Na, we need two NaHSO4. To balance Cl, we need two HCl.

    Na2SO3 + Cl2 + H2O → 2 NaHSO4 + 2 HCl

    The left side of this equation has four oxygen atoms, and the right side of this equation has four oxygen atoms. The left side of this equation has two hydrogen atoms, and the right side of this equation has two hydrogen atoms. This proves the equation is balanced. I hope this is helpful for you.
