2g of ethylenediamine tetraacetic acid (EDTA) are dissolvedin sufficient water to make a total volume of 1 liter. (ForEDTA: Mr = 292, pKa1 = 1.7, pKa2 =2.6, pKa3 = 6.3, pKa4 = 10.6)

a) What is the H+ ion concentration in thesolution?

b) What percentage of the EDTA molecules are ionized?

c) What is the pH of the solution?

d) If the EDTA had been dissolved in 100ml of 2.5M NaOH andsufficient water is added to make 1L, what major ionization formsof EDTA would be present? What would be the pH of the solution?
