3. 4. If 100.0 mL of a water sample is titrated with 0.01000 M EDTA, what is the titer of the EDTA in terms of water hardness/ mL? Calcium is determined in serum by microtitration with EDTA. A 100-L sample is treated with two drops of 2 M KOH, Cal-Red indicator is added, and the titration is performed with 0.00122 M EDTA, using a microburet. If 0.203 mL EDTA is required for titration, what is the level of calcium in
