Indirect iodimetry
WebO adsorbent was determined by indirect iodimetry. In an iodine-measuring flask, 1.0002 g of wet Ca(ALG) 2 –Cu 2 O was mixed with 5 ml of 6 mol l–1 HCl solution, followed by dropwise addition of 30% H 2 O 2 solution, until the colour of the solution did not change to ensure that Cu 2 O was completely oxidized into Cu2+. The concentration of ... WebTitration in which Iodine liberated during chemical reaction is titrated (Indirect Iodometric) 2I-- 2e-→ I. 2. 1. Iodimetry Titration: Principle: Iodimetry covers titration with a standard solution of iodine. Iodimetry deals with the titration of iodine liberated in chemical reaction. This method is based upon the inter conversion of ...

WebThe wide- spread use of direct and indirect iodimetry must be considered to be due in part to the sensitivity and sharpness of the starch—iodine reaction. Starch, however, cannot be used under a number of conditions; these include titrations in highly colored or strongly acidic solutions or at elevated temperatures.
