Ethylenediaminetetraacetic acid (EDTA), is one of the most popular chelating agents. It has two amino groups and four carboxylic acid groups. The structure of the most protonated form of EDTA can be designated as H6Y2* while the most deprotonated form can be designated as Y4. Given the pKa values of EDTA: 0.00, 1.50, 2.00, 2.69, 6.13, and 10.37, what is the predominating form at the following pH values? Choose from the following species: A. H,Y2+. C. H4Y D. H3Y E. H2Y2- F. HY3- G. Y4- B. H5Y* 8. At pH = 3.00 %3D Answer: [ Select] 9. At pH = 7.00 Answer: [ Select] 10. At pH = 11.00 Answer: [ Select ] >
