Analysis of Aluminum in a Mixture by Solvent Extraction and EDTA Titration. *the amount of EDTA, which is equivalent to the number of moles of zinc and the number of moles of aluminium.* A sample required 9.73 mL of zinc nitrate solution to titrate the EDTA released from aluminum through the addition of fluoride. If the molarity of the zinc solution was 0.025M and EDTA was 0.05M, what was the total weight of the aluminum present in the initial sample?
6. A solution contains 1.694 mg of CoSO4 (155.0 g/mol) per milliliter. Calculate(i) the volume of 0.08640 M EDTA needed to titrate a 25.00-mL aliquot of this solution.(ii) the volume of 0.009450 M Zn2+ needed to titrate the excess reagent after addition of 50.00 mL of 0.008640 M EDTA to a 25.00-mL aliquot of this solution.(iii) the volume of 0.008640 M EDTA needed to titrate the Zn2+ displaced by Co2+ following addition of an unmeasured excess of ZnY2- to a...

EDTA Titration 1. EDTA (cthylenediaminetetraacetic 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 Ca, Mg and other metal ions with EDTA. During the titration, ammonium-ammonia chloride buffer is often used. Which of the following descriptions about the function of ammonium-ammonia chloride is/are correct? (a) To react with EDTA To form...

1. Describe the differences you observed between the water, 4% EDTA, and 8% EDTA treatments.
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.
