WebEstimation of the total hardness of a water sample using edta Student Material. Theory. Ethylenediaminetetraacetic acid (edta) is a reagent that forms edta-metal complexes with many metal ions (but not with alkali metal ions such as Na + and K +).In alkaline conditions (pH › 9) it forms stable complexes with the alkaline earth metal ions Ca 2+ and Mg 2+. ... Webhardness of water is defined in terms of its content of calcium and magnesium ions. Since an analysis does not distinguish between Ca 2+ and Mg 2+ , and since most hardness is caused by carbonate deposits

WebMay 31, 2016 · In case of blank titration, the calculate volume of EDTA required by sample water, V = (V 1 -V 2 )ml. The total hardness (temporary + permanent) can be calculated by using the following formula. 1ml 0.01M EDTA ≡ 0.001001g CaCO 3. ∴ Vml 0.01M EDTA = V ᵡ 0.001001g CaCO 3. Now, 50ml of water sample ≡ V ᵡ 1.001mg CaCO 3.
