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. Note that iodometry involves indirect titration of iodine liberated by reaction with the analyte, whereas … Meer weergeven To a known volume of sample, an excess but known amount of iodide is added, which the oxidizing agent then oxidizes to iodine. Iodine dissolves in the iodide-containing solution to give triiodide ions, which have a dark brown … Meer weergeven Iodometry in its many variations is extremely useful in volumetric analysis. Examples include the determination of copper(II), chlorate, hydrogen peroxide, and dissolved oxygen: 2 Cu + 4 I → 2 CuI + I2 6 H + ClO−3 + 6 I → 3 I2 + Cl … Meer weergeven • Iodine–starch test Meer weergeven WebThe iodometric titration experiment help to determine the concentration of analyte that is used to produce iodine. ...
