Iodometric method dissolved oxygen
WebScore: 4.6/5 (50 votes) . Iodometry, 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. ...In an iodometric titration, a starch solution is used as an indicator since it can absorb the I2 that is released. WebDissolved oxygen can be measured by several common techniques, each with advantages and disadvantages. These methods include the iodometric method or Winkler titration method, amperometric measurements using gas-permeable membrane electrodes, and luminescence measurements using optical technologies.
