WebANALYTICA CHIMICA ACTA 541 HYDRAZINE AS A TITRIMETRIC REAGENT IN IODOMETRY PART I K. S. PANWAR, N. K. MATUUR AND S. P. RAO Department of Chemistry, Jaswant College, Jodhpw (India) (Received October i9th, 1960) Direct and indirect iodometric procedures are very widely used both in inorganic and organic … 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.
