For the following lab Complexometeric Determination of Magnesium... Mg^2+  +   Y^4-  -> MgY^2- Unknown MgO was titrated with roughly 0.03M of Na2EDTA and pH10 buffer solution (~5mL to MgO) using Nh4CL(s) and NH4OH, 8 drops of Calmigate Indictor and titrated to a blue endpoint with the EDTA (disappearance of the last tinge of red) 1. a. Why is it necessary to buffer the solution to a pH between 10 and 12? b. What is the structure and full name for EDTA? c. Although EDTA has, in its fully protonated form, 4 hydrogen atoms that can be lost, it is listed as a hexadentate ligand. Explain why this is the case

Spectroanalytical Methods

Spectroanalytical methods measure the wavelength and intensity of radiations that are either emitted or absorbed by a molecular or atomic species. These methods are useful for evaluating the electronic or atomic arrangement of the molecules of a given analyte.
