A solution sample may only contain Ag^+, Pb^2+, and Hg^2+ 2 ions. After the addition of 6 M HCl, a white precipitate forms. After centrifugation, the tube of solid was added to a beaker of boiling water. The tube was centrifuged. Acetic Acid and potassium chromate was added to the liquid that was separated from the solid residue and a bright yellow precipitate formed. The remaining solid residue dissolved when 6 M NH3 was added but no precipitate was formed. The solution was then acidified with 6M HCl and a white precipitate formed. Based on this info, justify your answers to these questions.
Pb is present, and Ag

is it Hg is missing
2. Which of the 3 possible ions are absent in the solution sample?
Titration of the lead and zinc in this aliquot required 34.06 mL of the EDTA solution. Finally, cyanide was used to mask the copper and the zinc in a 25.00 mL aliquot. Titration of the lead required 26.68 mL of the EDTA solution. Determine the com..
