Web15 feb. 1993 · The oxidation states of manganese in the La1−xMnO3−δ (x = 0.09–0.11) were investigated by electron spin resonance (ESR) and iodometry. The ESR analysis carried out at room temperature for the samples prepared in air revealed the presence of broad peaks at g = 2.0, considered to be relevant to Mn2+. It was also found that the … Webcator in iodometry since it provides evident colour change. However, sensitivity of this colour reaction decreases at high temperature, in the presence of organic solvent, and at low pH due to hydrolysis of starch. Starch is insoluble in cold water, so only fresh solutions should be used. It is suggested to apply starch solution just before the phoenix alcohol delivery

"WebWhat is Iodometric titration. Iodometric titration, also known as Iodometry, is a type of indirect titration. The analyte solution is an oxidizing agent in Iodometric titrations. It is reacted with an excess amount of potassium iodide (KI). The oxidizing agent oxidizes iodide (I–) ions into iodine (I2). " - Iodometry journal
