A 50.00mL water sample required 11.00mL of 0.1000 M EDTA to titrate the free Mg in a water hardness determination, given a sample pH = 10.00. Explain what was the concentration of Mg in the sample expressed as ppm Mg. The atomic weight of Mg is 24.30 g/mole.
Explain what was the Conditional Formation Constant for the formation of the EDTA complex for Mg under these conditions?(KMgY2- = 4.9*109)
