WebIodometry is the titration of iodine (I2) produced when an oxidizing analyte is added to excess I- (iodide). Then the iodine (I2) is usually titrated with standard thiosulfate solution. Iodometry: Not a direct titration because there are 2 reactions: analyte + I- → I2 unknown I2 + titrant (standard thiosulfate) product→ Known 42.
