EDTA Titration Calculations

Calcium ions can be analyzed by titration with EDTA using an appropriate indior. EDTA is ethylene diamine tetraacetic acid or H 4C 10H 12N 2O 4. EDTA itself is not very water soluble so the disodium salt is used, Na 2H 2C 10H 12N 2O 4. For the purpose of simplicity, Y will stand for C 10H 12N 2O 4. The EDTA we use is thus Na 2H 2Y. The part that
