A student was tasked to perform gravimetric analysis of a soluble sulfate. His unknown sample weighed 0.7543 g. The sample underwentprecipitation using BaCl2 and was digested for overnight. The precipitate was then filtered off to obtain white crystalline precipitate that was collected inan ash less filter paper. In performing constant weighing, he obtained a crucible mass that is 29.9442 g. After burning his samples inside the crucible,the obtained mass was 30.3375 g. Compute for the theoretical % SO3 obtained by the student and the theoretical mass (g) of SO3 that should be obtained by the student using his weighed sample

An analyst weighed 0.25045 g of the Buffalo River Sediment reference material.(RM # 8704) to determine Pb levels. The material was digested in an acid medium toBring it to a solution which was made up to the 30.2450 mL mark with distilled water. If thePb concentration in the control certificate of analysis is (150 ± 17) mg / kg, and theanalyst recovered 95%, what was the concentration of Pb in the solution?
A 0.53 g sample containing KBr (MW=119) is dissolved in 50 mL of distilled water. Titrating with 0.04614 N AgNO3 requires 28.5 mL to reach the endpoint. Calculate the %w/w KBr in the sample. (Round-off your answer to 2-decimal places) Answer = ____%
00 mL of a diprotic acid primary standard solution was accurately prepared to a concentration of 0.1431 M. Three samples of this primary standard solution were used as samples in a titration to standardize an aqueous solution of sodium hydroxide, NaOH, which would be used as a titrant. Using the following table of data for the titration of the primary standard acid with NaOH, calculate the average concentration of NaOH. Trial # Volume of primary standard Initial titrant volume Final titrant volume 1 10.00 mL 8.21 mL 27.22 mL 2 10.00 mL 27.22 mL 46.23 mL 3 10.00 mL 30.28 mL 49.29 mL 0.1506 M 0.0753 M 0.0376 M 0.1431 M 0.0526 M

A separate experiment showed that the molar mass of kobeicin is 170.25 g/mol. Calculate the percent purity of the kobeicin in the crude sample using the data from the second derivative plot.
How would the following errors change the calculated value of the percent oxalic acid in the radiator cleaner, that is would the calculated value of the percentage be high, low, or unchanged? Give a brief explanation of your reasoning. a. The experimenter consistently overshot the endpoint (i.e. added too much NaOH solution), of the titrations used to standardize the sodium hydroxide solution. b. The KHP used to standardize the NaOH was not pure, but contained approximately 10% by mass of the inert ionic compound potassium chloride, KCl. 3) Oxalic acid exists in the solid state as the monohydrate, H2C2O4•H2O. What would you use to calculate the percent oxalic acid monohydrate in the cleaner?
Potassium dichromate has several industrial applications. To determine the purity of the salt that will be used in different industrial processes, a sample mass equal to 2.660 g was dissolved and quantitatively transferred to a 500.00 mL flask. An aliquot of 25.00 mL of this solution was treated with excess KI and the released iodine was titrated with 0.1000 mol L-1 sodium thiosulfate, spending 27.00 mL. Calculate the purity of the analyzed salt. Data:K = 39.10 O = 16.00 Cr = 52.00 I = 126.9 S = 32.07
