What is the reaction & calculation when KIO3 mixed with KI, HCl by titration with Na2S2O3?

  • Analytical chemistry - ,

    5KI + 6HCl + KIO3 ==> 3I2 + 3H2O + 6KCl
    I2 + 2Na2S2O3 ==> 2NaI + Na2S4O6
    Here are the equations for the liberation of I2 and titration of same with thiosulfate. If you can't work the problem(s) from here, post with the numbers and a clear explanation of what you don't understand.
