Discussions EDTA titration of Calcium and Magnesium in Natural Water of the report. Find out any discrepancy between results and objectives, any achievements should be discussed in light of the intended objectives. Usually, your results fall short of the expected one and you should identify where the gaps are. In these cases, suggest whether it arises from the experimental procedure, set-up of instrument, purity of chemicals, design of method and results, you should give explanations of the errors with evidence. Furthermore, you should suggest ways to improve the results. Using Reagent 1. Calcium carbonate ~ 0.5 gm 2. HCl solution (6 M) 3. NH4OH (3 M) 4. Methyl red indicator 5. Sample(s) of water of appropriate hardness (in region of 150-200 mg.l-1) (see note below) 6. pH 10 buffer 7. EDTA solution (~0.02 mol.l-1 ) 8. Eriochrome Black T indicator 9. Distilled water Answer

PROCEDURE Acidity 100 mL aliquots of the sample with a few drops of HCI, and boil gently for a few minutes to eliminate CO2. Cool, add 3 to 4 drops of methyl red, and neutralise with 0.1 M NaOH. Introduce 2 ml of pH-10 buffer, 3 to 4 drops of Eriochrome Black T, and titrate with the prepared standard NazHzY to a colour change from red to pure, blue (Note). Report the results in terms of milligrams of CaCO; per litre water. NOTE The colour change is sluggish if Mg? is absent. In this event, add 1 to 2mL of 0.1 Mg Y2- before starting the titration (see Section 36D-4 for the preparation of this solution). Data.
