http://www2.csudh.edu/oliver/che230/labmanual/copbrass.htm WebThere are numerous end-point detection techniques in iodimetric titration. It is observed that even a small drop of 0.05 mol L–1 iodine solution added to 100 mL of water causes the colour changes into pale-yellow. If more iodine solution is added, the mixture becomes brown. If some organic solvents, for example chloroform or

WebIodometric Titration Method Iodometric titration assay, which is based on the oxidation of the iodide ion (1 ) by hydroperoxides (ROOH), is the basis of current standard methods for determination of PV (9). In this method, a samrated solution of potassium iodide is added to oil samples to react with hydroperoxides. WebOriginally developed by Ion Atanasio, cerimetry or cerimetry titration is a volumetric chemical analysis technique. This titration is a redox reaction where a change in the color of the Fe-1,10-phenanthroline complex (ferroin) indicates the endpoint. By titrating ferroin with a Ce solution, ferroin can be reversibly discolored in an oxidized state.
