The Professor demonstrated the proper application of the procedure by analyzing a 50 mL sample of water from a local lake (Rivers Parkway) via titration with a standard solution of EDTA 0.0100 +0.0001 M standard. This sample consumed 5.00 mL to reach the Total Hardness (TH) end point; therefore, the TH of the lake was determined to be XX ± YY mg/L as CaCO,.
