Potassium permanganate AR

  1. Hi
    new here
    A level assessed practical titration of potassium permanganate - there is AR grade in stock and they use that, but I want to buy more and can't see it in any of the catalogues (the only ones that list the grade give LR).

    Does anyone buy AR, and where from?
     
  2. You can get Potassium Manganate (VII) AR from Philip Harris.
     
  3. LR is sufficient for your Pre-University intended use.:)

  4. thanks
    Yes, that does make sense from the lack of differentiation of grades - but not my call at the moment!
