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 … 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
