Write a balanced net ionic equation for the following reaction?

Write the balanced net ionic equation for the following reaction in basic solution...?

  • S2O3^2-(aq) + I2(aq) --> S4O6^2-(aq) + I^-(aq) I'm usually pretty good with redox reactions but I just can't seem to get this one? Could you please show me what to do :3

  • Answer:

    S2O3^2-(aq) + I2(aq) --> S4O6^2-(aq) + I^-(aq) 2S2O3^2- --> S4O6^2- + 2e- I2 + 2e- --> 2I- ------------------- ------------------- 2S2O3^2 + I2 --> S4O6^2- + 2I- That was easy. You don't have to worry about balancing any oxygen atoms with water and OH-.
