A sample contains Pb2+, Mg2+ and Zn2+. 0.4085 g of the sample is weighed and dissolved. Once dissolved it is with cyanide to form a complex and mask the zinc (Zn2++ 4 CN-→ Zn (CN)4 2-). The Pb2+ and Mg2+ in the solution are titrated with 42.22 mL of EDTA 0.02604 M. Then the Pb complex is treated with another organic ligand that masks Pb and releases EDTA, which is titrated with 19.35 mL of a Mg2+ 0.007657 M solution. For finalize formaldehyde is added to unmask the Zn2+(Zn (CN)4 2- + 4 HCHO + 4 H2O → Zn2+ + 4 HOCH2CN + 4 OH-). The liberated zinc is titrated with EDTA 0.02064 M consuming 28.63 mL. (Data: Pat Pb, 207.22; Pat Mg, 24.31; Pat Zn, 65.4). Find the percentage of the three metals in the sample.

PLEASE I NEED TO UNDERSTAND HOW TO SOLVE THIS. A 1.000-gram sample of NaOH (39.997 g/mol) which has been exposed to the air for some time (NaOH will adsorb water and CO2 from the ambient air) is dissolved in water and then diluted to 500.00 mL, 100.0 mL of this solution required 38.60 mL of 0.01062 M HCl to be titrated to a methyl orange endpoint (~pH 3). A second 100.00 mL portion is treated with excess BaCl2 and then diluted to 250 mL and filtered. 200 mL of the filtrate required 29.62 mL of HCl to titrate to phenolphthalein (~pH 8-9) endpoint. Calculate in the original sample:a.) the percentage of NaOHb.) the percentage of Na2CO3 (105.9898 g/mol)Make sure you use at least four significant figures for this calculation. Note that the adsorbed CO2 is converted to Na2CO3. The Ksp for BaCO3 (s) is 2.58 x 10-9 (extremely insoluble).
