  • Also used to monitor diazotization reactions
  • Oxidising agents react with potassium iodide to produce elemental iodine which in turn reacts with the starch to form a blue-violet colour reaction
  • The paper can be dipped into the sample or drops can be placed on it
  • The paper is moistened with distilled water to detect oxidising gases

Open the the casing and remove one of the paper's from a book. Dip the paper into your test solution for around 2 seconds, and then check the paper for a result.
