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 … WebThe term “iodometry” describes the type of titration that uses a standardised sodium thiosulfate solution as the titrant, one of the few stable reducing agents where oxidisation of air is concerned. Iodometry is used to determine the concentration of oxidising agents through an indirect process involving iodine as the intermediary. the other 98% bias https://ponuvid.com
