A 12.63 g sample of calcium ore was dissolved in HCl and gravimetrically analyzed, through the precipitation of calcium into CaC2O4 · H2O. The precipitate was filtered, washed, dried, and ignited at 500 oC until the weight was constant, giving a final mass of 2.35 grams pure CaCO3 (100.087 g/mol). Calculate the % Calcium (40.078 g/mol) in the sample.
Summary of Level of Saturation in chemistry solutions
Which among the statements to promote large precipitates is INCORRECT? Having a dilute solution will keep supersaturation ratio small. Temperature affects particle size during crystal growth. The order of addition of the precipitating reagents may affect induction period. It is better to have a faster rate of nucleation than the rate of crystal growth.
3) 2.413 g sample contains Na CO, NaHCO and inert material. This sample was solved in water and diluted to 250.0 ml. 80 ml solution was taken and titrated with 0.09644 N HCl with the indicator of phenolftalein. 6.13 ml HCl was consumed. From a second solution, again 80 ml was taken and titrated with the same HCl solution with the indicator of methylorange. 15.4 ml HCl was consumed. Calculate the percentage of NaHCO and Na CO in sample (Na_CO_=106.0 g/mol, NaHCO =84.02 g/mol). 2 2 3 3
Gravimetric Analysis. Please include complete solution, thank you. In the gravimetric determination of sulfate in a 0.2841 g sample of pure Na2SO4, a BaSO4 precipitate weighing 0.4604 g was obtained. The weight of the precipitate was smaller than the theoretical one, since some BaSO4 was converted to BaS during the heating process. Calculate the percent of BaS in the precipitate and percent error of the analysis.
A 1.461 g sample containing K2SO4, NH4Cl, and inert materials was dissolved in sufficient water to give exactly 250 mL of solution. A 25.0 mL aliquot of this solution yielded 0.299 g of precipitate that consisted only of (C6H5)4BK and (C6H5)4BNH4. Another 50.0 mL aliquot of the solution gave 0.3230 g (C6H5)4BK only. Calculate the mass percent of K2SO4 and NH4Cl is the sample.
Q1)a) In the gravimetric analysis the precipitate should be free from impurities. Give the detailed justification for the above statement by identifying impurities. b) It is required to analyse the metal from its ore sample. Manganese (Mn)present in the ore sample was analysed by forming a precipitate of MnSO4. If 2.98 g of ore sample gives 0.19 g of MnSO4. Calculate the percentage of Mn present in the sample.
