    Determining the concentration of an unknown solution
    This is not "homework" as such. It's for a science competition and we can do research. Here's the layout and materials given.

    Q: Experimentally determine the concentration of a solution of Potassium
    Permanganate (KMnO4).

    Materials:

    5 - standard size test-tubes
    1 evaporation dish
    1 burette
    250 ml beaker
    Digital balance
    20.0g of solid KMnO4
    100.0 ml of heated acidified sodium oxalate solution of known concentration
    2 - 250 ml Erlenmeyer flask
    1 graduated cylinder
    1 hotplate
