What is EDTA Titration for Water Hardness Analysis about?

This document describes a laboratory experiment to determine water hardness using complexometric titration with EDTA. [1] Students standardized an EDTA solution by titrating it against a calcium carbonate solution of known concentration and calculated the molarity. [2] They then used the standardized EDTA to titrate water samples to determine calcium concentration and hardness in mg/L CaCO3. [3] Additional techniques like spectrophotometry were used and results from different methods were compared.
