A sample is analyzed for chloride by the Volhard method. Calculate the %KCl from the following data: Wt of sample = 0.5000g; Vol of AgNO3 added = 35.00ml; M of AgNO3 = 0.1157; Vol of SCN- used for back titration = 14.71ml; M of SCN- = 0.08598; Atomic wts: Ag = 107.87, N = 14.00, Cl = 35.5, O = 16.00
A 1.000-g sample containing bromide was dissolved in sufficient water to give 100.0 mL. A 50.00 mL aliquot was measured and after acidification, silver nitrate was introduced to precipitate AgBr, which was filtered, washed, and then dissolved in an ammoniacal solution of potassium tetracyanonickelate(II): Ni(CN)42- + 2AgBr(s) → 2Ag(CN)2- + Ni2+ + 2Br-Nickel ion required 11.70 mL of 0.002146 M EDTAWhat is the percentage of NaBr (102.894) in the 1.000 g sample?
Please answer this NEATLY, COMPLETELY, and CORRECTLY for an UPVOTE. CuSO4From the stock solution (0.040 M), pipet 0.00, 2.00, 5.00, 10.00, 15.00 and 20.00 aliquots into 100 mL volumetric flasks. Develop the color (royal blue) by adding enough NH3 solution to form Cu(NH3)42+ complex. Add 10 mL excess to stabilize to complex. Dilute to the desired volume. Determine the concentration of each standard solution and tabulate. *I'm not sure if a Dilution Factor (DF) is still needed in here but I hope you can also explain this if DF is still needed in the computation.

TRUE OR FALSE: Because of chelate effect, the formation reaction of the complex tris(ethylenediamine)cobalt(III) has a smaller negative ΔGrxn and a larger positive ΔSrxn compared to the formation of hexaamminecobalt(III).
A second calibration standard solution of an iron(III) salicylate complex was prepared in two steps. First, 10.0 mL of a 0.100 M stock solution was added to 90.0 mL of solvent to make 100.0 mL of the first calibration standard solution and, secondly, 80 mL of that first calibration solution plus 20.0 mL of solvent were mixed to make the second calibration standard. What is the concentration of the second calibration standard solution?

Aluminium (III) reacts with the Chelating agent HL to give a complex AlL3 that is readily soluble in CHCl3. A spectrophotometric study shows that when a 1.77 x10-4 M aqueous solution of aluminium was extracted with CHCl3 containing 0.01M HL, the analytical concentration of aluminium at pH 4.5 in the two phases were 1.5 x 10-4 M [Al3+]upper) and 2.73 x10-5 M ([AlL3]lower) . What is the distribution coefficient at pH 4.8.
