if 361.3 mg of Li2(SO4) (FW=109.95) is added to 450 mL of 0.828 M NH4F, what is the Qip for lithium fluoride. (Ksp of lithium fluoride= 3.8 x10^-3)
Calcium fluoride is considered as a relatively insoluble compound and therefore lime or slakedlime has been considered as a possible material to remove excess fluoride in water of boreholesin certain parts of the country. The solubility product of CaF2 is Ksp = 3 x 10 – 11 and that ofCa(OH)2 isKsp =8x10-61. How much lime can be added to the water to remove 10 mg of F- ion per litre ofborehole water?(The atomic masses are Ca: 40.08; F: 19.00; O: 16; H: 1)
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.
The SO2 present in air is mainly responsible for the phenomenon of acid rain. The concentration of SO2 can be determined by titrating against a standard permanganate solution as follows: 5SO2 + 2MnO4- + 2H2O ---> 5SO42- + 2Ms2 + 4H+ Calculate the number of grams of SO2 in a sample of air if 4.90mL of 0.00700M KMnO4 solution are required for the titration. Be sure your answer has the correct number of significant digits.
In the determination of water hardness by volumetry, AEDT is used. If the volume of 0.01 M EDTA used to titrate 100 mL of sample was 20 mL, calculate the total hardness expressed in mg/L of CaCO3.
Twenty sodium salicylate tablets labeled 325 mg were dispersed in sufficient water to make 200.0 mL. A 15.0–mL aliquot of the filtrate was titrated to a bromophenol blue endpoint in the usual way by 32.11 mL of 0.1000 N hydrochloric acid. Calculate the amount of sodium salicylate in each tablet, and from that, the percentage of the labeled amount.
