The reaction between IO3-and I-is given as 6H++IO3-+5I---- >3I2+3H2O Reactions Involved in Iodometric Processes Iodometric methods depend on the following equilibrium: I2+ I-<===> I3- Web20 Jan 2014 · At pH ≳ 11, triiodide disproportionates to hypoiodous acid (HOI), iodate, and iodide. • An excellent way to prepare standard I3- : is to add a weighed quantity of potassium iodate to a small excess of KI. Then add excess strong acid (giving pH ≈ 1) to produce I2 by quantitative reverse disproportionation: IO3- + 5I- + 6H+ ⇋ 3I2 + 3H2O legendary stick vesteria
