Direct titration of I_(2) with a reducing agent is called iodimetry. If I_(2) is leberated by the oxidation of I_(ɵ) ion by a strong oxidising agent in neutral or acidic medium, the liberated I_(2) is then titrated with reducing agent. Iodometry is used to estimate the strngth of the oxidising agent. For example, in the estimation of Cu^(2+) with S_(2)O_(3)^(2-) Cu^(2+)+I^(ɵ)toCuI_(2)+I_(2) (iodometry) I_(2)+S_(2)O_(3)^(2-)toS_(4)O_(6)^(2-)+I^(ɵ) (iodimetry) Strach is used as an indicator at the end point, which forms bluecoloured complex with I_(3)^(ɵ) Disappearance of blue colourindicates the end point whe free I_(2) in not present.
