Determination of hardness of water by edta
WebThe water hardness determination by EDTA experiment is very common for intro/analytical chem labs and it's usually set up so that you need to subtract the total hardness (combined concentration) by the concentration of one of the metals to get the concentration of both metals. This tests your titration skills as well as being able to follow … WebDetermination of water hardness by EDTA titration. Theory: Water hardness may be defined as the content of dissolved magnesium, calcium salts and also several other elements from the Mendeleev periodic table. E.g., these can be iron and manganese salts but the content of the latter in water is, as a rule, less by one order as compared to …

WebJul 5, 2024 · Calculations: The following calculation are adopted: Hardness (mg/L)= (EDTA Volume S 1000)/V. Where, S is the quantity of CaCO 3 equal to 1mL of the titrant adopted. V is the total volume of the sample. Hardness (mg/L)= (EDTA Volume 1000)/V. WebYou will then use the EDTA solution to determine the hardness of an unknown water sample. Since both EDTA and Ca2+ are both colorless, it is necessary to use a rather special indicator to detect the end point of the titration. The indicator you will employ is called Eriochrome Black T, which forms a rather stable wine-red complex, MgIn-, 1
