2. Ethylenediaminetetraacetic acid (EDTA) is used for a range of applications because of its ability to strongly bind metal ions via its six ligating groups. EDTA is used in the paper industry to bind Mn2+ (and other metal) ions from catalyzing the decomposition of hydrogen peroxide (H2O2), which is an important chemical for bleaching the pulp. In this example, we are going to focus on the chelation of free Mn2+ ions in a solution at pH = 7. a) If...

EDTA (ethylenediaminetetraacetic acid), a widely used complexing agent, is a tetraprotic acid with the following pK_a values: pK_a1 = 2.16; pK_a2 = 3.12; pK_a3 = 6.27; pK_a4 = 10.95. Write the expressions for alpha_1, alpha_2, alpha_3, and alpha_4 and determine the numerical value of each at pH 7.0.

EDTA (ethylenediaminetetraacetic acid) is the most widely used metal chelator in analytical chemistry, which forms strong 1:1 complexes with most metal ions. Water hardness can be determined by titrating Ca2+, Mg2+ and other metal ions with EDTA. During the titration, ammonium-ammonium chloride buffer is often used. Which of the following descriptions about the function of ammonium-ammonium chloride is/are correct? To act as a masking agent To form complex with Ca2+ and Mg2+ To be used as a metal ion indicator...

10. EDTA (C10H16N208) is an aminopolycarboxylic acid, widely used for scavenging metal ions. EDTA has high denticity, and can displace the H2O ligands that bind to hydrated metal cations. For example: [Fe(H2O).]3+ (aq) + EDTA (aq) → Fe-EDTA'(aq) + 6H20 (1) Explain conceptually, what you think drives the aforementioned reaction (enthalpy or entropy), and why.

11. Ethylenediamminetetraacetic acid (EDTA ) binds metals ions to form complexes, thus can be used to determine concentrations of metal ions, as well as for use in chelation therapy. Calculate the concentration of [Co2] in solution after the addition of 48.0 mL of 0.050 M EDTA to a 50.00-ml sample of 0.048 M [Co]. 10 pts

Nitrilotriacetic acid is a tetraprotic acid and a tetradentate
ligand, that unlike EDTA is biodegradable. It is used as a water
softener in detergents to bind multiply charged cations such as
Ca2+ and Fe3+. K1 = 0.100; K2= 1.55E-2; K3=3.02E-3; K4=3.47E-10.
The active species for binding metals is the tetradeprotonated
form, so calculate α4for pH = 8.847. (the
pH's have 3 significant figures in case the trailing zero is
lost)
