http://chemistry.csudh.edu/oliver/che230/labmanual/copbrass.htm 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.
WebIodometry, known as iodometric titration, is a method of volumetric chemical analysis, a redox titration where the appearance or disappearance of elementary iodine indicates the end point. What happens when iodine is titrated with thiosulfate solution? ... Titrate until the endpoint is reached. Web6 mei 2024 · A starch solution can then be used as a color-change indicator to detect the titration endpoint. In this case, the solution begins blue and disappears at the endpoint when the iodine is all reacted. Types of Redox Titrations Redox titrations are named according to the titrant that is used: Bromometry uses a bromine (Br 2) titrant.
