Volumetric Analysis
  1. Titrating EDTA with magnesium and calcium ion using eriochrome black T.
    1. End point :
      1. Red
        1. to blue
        2. EDTA in the burette
          1. Pipette 25ml portions of the magnesium solution under test into a conical flask.
            1. Add 10ml of pH10 buffer
              1. Add 4/5 drops of the indicator, eriochrome black T. Titrate the ion solution with edta
              2. Titrating acidified potassium manganate(VII) with Iron (II)
                1. Potassium Manganate (VII) in the burette
                  1. Pipette 25ml portions of ammonium iron (II) sulfate into a conical flask
                    1. Add 10ml of dilute sulfuric acid.
                      1. End point :
                        1. Colourless
                          1. to pink
                      2. Titrating Iodine with sodium thiosulfate ions using starch as an indicator
                        1. Estimate oxidising agents such as hydrogen peroxide and iodate ions by their reactions with potassium iodide
                          1. Add the thiosulfate until the solution is straw coloured.
                            1. Add starch at this point and the solution will change from
                              1. BLUE-BLACK
                                1. to colourless
