Iodimetry iodometry 차이
WebIodine readily reacts with many organic and inorganic substances. Iodometry can be used both to determine amount of reducing agents (by direct titration with iodine) and of oxidizing agents (by titration of iodine with thiosulfate). End-point determination is based on the presence of a blue starch complex. WebIodimetry definition, iodometry. See more. There are grammar debates that never die; and the ones highlighted in the questions in this quiz are sure to rile everyone up once again.

WebIodine is one of the most popular reagents in a chemical analysis. In iodometry, it is used as a titrant in a direct titration, as well as in the indirect titration, which is based on the reaction between strong oxidizing agents and a large excess of iodide ions to produce iodine in the amount equivalent to the analyte. Iodine is subsequently WebThis category of assay is termed as ‘residual method of iodimetry’. In iodometry, an equivalent amount of iodine is liberated when the given sample of an oxidizing agent oxidizes potassium iodide in an acidic medium, for example : the determination of cupric sulphate (CuSO4) : 2CuSO4 + 4 KI → 2CuI ↓ + I2 + 2K2SO4
