Determination of the hardness of water lab
WebIntroduction Water hardness can be determined by performing a titration experiment with a complexing agent, this titration is known as a complexometric titration. Complexometric titrations are titrations that coordinate complexes between a metal ion and complexing agent also known a s a chelating agent (1). Complexometric titrations are performed to indicate … WebTesting for Water Hardness Background Info: Hard water has a lot of minerals (Calcium and Magnesium mainly) dissolved in it.

WebThe hardness may range from zero to hundreds of milligrams per litre in terms of calcium carbonate, depending on the source and treatment to which the water has been subjected. Ethylenediamine tetra-acetic acid and its sodium salts (EDTA) form a chelated soluble complex when added to a solution of certain metal cations. 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.
