11 (I)- + IO3- + 6 H+ → 6 (I2)- + 3 H2O

This is an oxidation-reduction (redox) reaction:

11 I-I - 11/2 e- → 11 I-1/2 (oxidation)

IV + 11/2 e- → I-1/2 (reduction)

I- is a reducing agent, IO3- is an oxidizing agent (synproportionation (comproportionation)).

Reactants:

  • I-
  • IO3-
  • H+

Products:

  • I2-
  • H2O – Water, oxidane source: wikipedia, accessed: 2019-09-27
