A 5.5984 g sample of soil was analyzed for lead. The sample was digested in hot perchloric acid for 5 hours, cooled, filtered to remove insoluble silicates, transferred to a 250-ml volumetric flask and diluted to the mark with distilled water. A 50.00-ml portion of the resulting solution was treated with phosphoric acid (H3PO4) forming 0.0862 g of precipitate. What was the weight % of lead? 3 Pb2+ + 2 PO43- ® Pb3(PO4)2(s)

A stainless steel alloy is to be analyzed for its chromium content. A 3.00 g sample of the steel is used to produce 250.0 mL of a solution containing Cr2O72−. A 10.0-mL portion of this solution is added to BaCl2(aq). When the pH of the solution is properly adjusted, 0.145 g BaCrO4(s)precipitates. What is the percent Cr, by mass, in the steel sample?

A sample of wine was diluted 1:10 and analyzed for alcohol content. A calibration curve was created from a set of standard solutions producing a plot of absorbance vs. percent alcohol. The calibration curve had a slope of 8.07 x 10-2 with an intercept of 6.02 x 10-3. Keeping in mind that the wine sample was diluted by a factor of ten, what is the percent, by volume, of alcohol in your sample if the absorbance of your sample was...

A sample is analyzed to determine its iron content Fe2+ via a redox titration with potassium chromate as the titrant. In the titration Fe2+ is oxidized to Fe3+ and CrO4 2- is reduced to Cr 3+. What is the percent by mass of iron in the sample if 0.9087g of the sample required 45.68mL of a 0.04322 M K2CrO4 solution to reach the endpoint? I worked out the balanced equation to be: 8H+ + 3Fe2+ + CrO4 2- = 3Fe3+...

Primary clarifier effluent was analyzed for solids content by an analytical laboratory. A 250-mL sample of the effluent was filtered through a laboratory (1 micrometer) filter. A 241-mL sample of the filtrate contained 89 mg of salts as dissolved solids (Residue 1). Solid residue from the filtration was dried overnight at 105 deg C and weighed 37 mg (Residue 2). What were the concentrations of total dissolved solids, total suspended solids, and total solids in the primary clarifier effluent? Water...

A water sample obtained from the neigborhood pond was analyzed for dissolved oxygen content. A volume of 300 mL, with temperature 21 degrees Celsius, was analyzed using the Wrinkler method shown in the simulated lab material. It took 15.0 mL of 0.01 mol/L Na2S2O3 solution to reach titration end point. *Note: Na2S2O3 solution is the source of S2O32- ions for the titration reaction. In the succeeding questions, provide the following values required. Take note of the units a.What is the...

A 25.0-mL sample of lambic (a sour Belgian beer) was analyzed for its acetic acid content by an electrochemical method. The pure sample registered a signal of 2.55 mA. A standard solution of 0.500 mL of 0.109 M acetic acid was added, and the signal increased to 2.98 mA. What is the acetic acid concentration in the original lambic sample?

A 7.279 gram sample of meat was analyzed for its nitrogen content using kjeldahl method. Upon digestion, the ammonia liberated was collected in 250 ml of 0.855 M H3BO3. The resulting solution was titrated with 37.25 ml of 0.3122 M HCl using mixed indicator. Determine the % protein in the sample using 6.25 as a factor for meat product ? Answer: 13.98%

You wish to determine the amount of lead in a drinking water sample (500mL). It is possible that sulfate in the sample (as well as other ions) will produce a matrix effect that will compromise the analysis, so you use a standard addition calibration method. You transfer 15 mL of your sample into each of five 50 mL volumetric flasks. You add the following volumes of a 5 ppm lead standard to the 5 flasks : 0, 5, 10, 15,...
