About this document
Total Hardness by adilkhan728820 is a document available to read on EtoBox.
The experiment aims to determine the total hardness of a water sample through complexometric titration using M/100 EDTA solution and Eriochrome Black T as an indicator. The procedure involves titrating both a known solution of M/100 CaCO3 and an unknown tap water sample until a color change indicates the endpoint. Results will provide the total hardness in terms of CaCO3 equivalent, expressed in gm/litre and ppm.
