  2. Melzer's reagent - Wikipedia

    en.wikipedia.org/wiki/Melzer's_reagent

    Melzer's reagent is an aqueous solution of chloral hydrate, potassium iodide, and iodine.Depending on the formulation, it consists of approximately 2.50-3.75% potassium iodide and 0.75–1.25% iodine, with the remainder of the solution being 50% water and 50% chloral hydrate.

  3. Iodometry - Wikipedia

    en.wikipedia.org/wiki/Iodometry

    The iodometric titration is a general method to determine the concentration of an oxidising agent in solution. In an iodometric titration, a starch solution is used as an indicator since it can absorb the I 2 that is released, visually indicating a positive iodine-starch test with a deep blue hue. This absorption will cause the solution to ...

    A bottle of iodine solution used on apples to determine the correct harvest time. The chart shows the level of residual starch. The cut surface of an apple stained with iodine, indicating a starch level of 4–5. The iodine–starch test is a chemical reaction that is used to test for the presence of starch or for iodine. The combination of ...

  5. Redox titration - Wikipedia

    en.wikipedia.org/wiki/Redox_titration

    A redox titration [1] is a type of titration based on a redox reaction between the analyte and titrant. It may involve the use of a redox indicator and/or a potentiometer. A common example of a redox titration is the treatment of a solution of iodine with a reducing agent to produce iodide using a starch indicator to help detect the endpoint.

    en.wikipedia.org/wiki/Ripper_Method

    The Ripper Method, developed in 1898, [1] is an analytical chemistry technique used to determine the total amount of sulfur dioxide (SO 2) in a solution.This technique uses iodine standard and a starch indicator to titrate the solution and determine the concentration of free SO 2.
