EDTA titration of CaCO3
« on: September 26, 2011, 05:32:35 PM »
How do you calculate the Molarity of EDTA with the following information:

Mass of CaCO3, Volume titrated (EDTA), pH~ 11-12 (indicator used was murexide)

Would you do a simple stoichiometric calculation or do you need to consider a bunch of other things like on this webpage

This is simple stoichiometry. Those other things make sense when you calculate titration curve.
