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
