    The purpose of this lab was to see which solutions are soluble and which are not. We were able to see this by mixing certain solutions together and observing changes that occurred. The procedure for this experiment included a few different steps. The first steps were to add the nitrate solutions into the lettered parts of the 96-well plate. Once you were done with that‚ you were supposed to add the sodium solutions to the numbered parts of the 96-well plate‚ so that the solutions were added together

    MnO4¯ + 5 Fe+² + 8H+ → Mn+² + 5 Fe+³ + 4H2O (3) Potassium permanganate is widely used as an oxidizing agent in volumetric analysis.Since the MnO4 ion is a deep pink-violet colour and the Mn2+ ion is nearly colourless‚ the end point in titrations using KMnO4 can be taken as the first pink colour that persists in the solution. In titration ‚ permanganate solution is put in the burette and is run down to an acidified solution of reducing agent‚ e.g..ammonium iron(II) sulphate
