10.) A 0.6025 g sample was dissolved and the Ca 2+ and Ba 2+ ions present were precipitated as BaC₂O₁.H₂O and CaC₂O4.H₂O. The oxalates were then heated in a thermogravimetric apparatus leaving a residue that weighed 0.5713 g in the range 320 °C to 400°C and 0.4674 g in the range 580°C to 620°C. Calculate the percentage Ba in the sample.

A piece of Gold weighing 12,359 Kg is suspected of being contaminated with Iron. To perform an instrumental analysis and To confirm whether or not it contains Fe, a portion of the sample (0.954 g) is taken from the piece and dissolved with 25 mL of aqua regia. Heats up For its complete dissolution, it is cooled and made up to 100 mL. A 10 mL aliquot is taken from this solution and made up to 50 mL. From This last solution is given the appropriate treatment to visualize Fe+2, for which the 1,10-phenanthroline reagent is added. (it forms a complex that is red in color) and is taken to a visible spectrophotometer and with a 12 mm cell a absorbance of 0.45. Previously, a calibration curve of Fe+2 was obtained under the same instrumental conditions obtaining the following data: (view table) Calculate the purity of the gold piece, assuming impurities only due to Fe.
A saturated AgClAgCl solution was analyzed and found to contain 1.25 x 10-5 M Ag+AgX+ ions. Use this value to calculate the Ksp of AgCl
A sample containing BaCl, 2H,0, KCI and inert material weighed 0.8417 g. After heating the sample at 160°C for 45 min, it weighed 0.8076 g.

250.0 ml of the mineral water sample was precipitated with potassium sodium tetraphenyl bromate: K+ + B(C6H5)4-  KB(C6H5)(s). The precipitate was filtered, washed and dissolved in an organic solvent. An excess of HgY2- was added to the solution: 4 HgY2- + B(C6H5)4- +4H2O  H3BO3 + 4C6H5Hg+ + 4HY3- + OH-. The liberated EDTA was titrated with 0.05581 M Mg 2+ solution, which consumed 29.64 mL. Calculate the potassium concentration [mg/l] in the sample.
Oral rehydration salts are stated to contain the following components: Sodium Chloride 3.5g Potassium Chloride 1.5g Sodium Citrate 2.9g Anhydrous Glucose 20.0g 8.342 g of oral rehydration salts are dissolved in 500 ml of water. 5 ml of the solution is diluted to 100 ml and then 5 ml is taken from the diluted sample and is diluted to 100 ml. The sodium content of the sample is then determined by flame photometry. The sodium salts used to prepare the mixture were: Trisodium citrate hydrate (C6H5Na3O7, 2H2O) MW 294.1 and sodium chloride (NaCl) NW 58.5. Atomic weight of Na = 23.
