EDTA Titration Calculations

concentration of Ca2+ ions is usually expressed as ppm CaCO 3 in the water sample. This is equivalent to 1 gram of CaCO 3 in 10 6 grams of sample. In the lab 1 ppm CaCO 3 is expressed as 1 mg CaCO 3 per 1 Liter of sample or ppm is mg CaCO 3 per L of sample. Calcium ions can be analyzed by titration with EDTA using an appropriate indicator.
