Lead poisoning has been a hazard for centuries. Some scholars believe that the decline of the Roman Empire can be traced, in part, to high levels of lead in water from containers and pipes, and from wine that was stored in leadglazed containers. If we presume that the typical Roman water supply was saturated with lead carbonate, PbCO3 (Ksp = 7.4 1014), how much lead will a Roman ingest in a year if he or she drinks 1 L/day from the container?
On Easter Sunday, April 3, 1983, nitric acid spilled from a tank car near downtown Denver, Colorado. The spill was neutralized with sodium carbonate: 2HNO3(aq)+Na2CO3(aq)2NaNO3(aq)+H2O(l)+CO2(g) a. Calculate H for this reaction. Approximately 2.0 104 gal nitric acid was spilled. Assume that the acid was an aqueous solution containing 70.0% HNO3 by mass with a density of 1.42 glcm3. What mass of sodium carbonate was required for complete neutralization of the spill, and what quantity of heat was evolved? (Hf for NaNO3(aq) = 467 kJ/mol) b. According to The Denver Post for April 4, 1983, authorities feared that dangerous air pollution might occur during the neutralization. Considering the magnitude of H, what was their major concern?
Gold metal will dissolve only in aqua regia, a mixture of concentrated hydrochloric acid and concentrated nitric acid in a 3:1 volume ratio. The products of the reaction between gold and the concentrated acids are AuCl4-(aq), NO(g), and H2O. The equation for this reaction where HNO3 and HCl are strong acids is Au(s)+4Cl(aq)+4H+(aq)+NO3(aq)AuCl4(aq)+NO(g)+2H2O(a) What stoichiometric ratio of hydrochloric acid to nitric acid should be used? (b) What volumes of 12 M HCl and 16 M are HNO3 required to furnish the Cl- and NO3- ions to react with 25.0 g of gold?
The vanadium in a sample of ore is converted to VO2+. The VO2+ ion is subsequently titrated with MnO4 in acidic solution to form V(OH)4+ and manganese(II) ion. The unbalanced titration reaction is MnO4(aq)+VO2++(aq)+H2O(l)V(OH)4+(aq)+Mn2+(aq)+H+(aq) To titrate the solution, 26.45 mL of 0.02250 M MnO4 was required. If the mass percent of vanadium in the ore was 58.1 %, what was the mass of the ore sample? Hint: Balance the titration reaction by the oxidation states method.
68. Aluminum ion may be precipitated from aqueous solution by addition of hydroxide ion, forming Al(OH)3. A large excess of hydroxide ion must not be added, however, because the precipitate of Al(OH)3 will redissolve as a soluble compound containing aluminum ions and hydroxide ions begins to form. How many grains of solid NaOH should be added to 10.0 mL of 0.250 M A1Cl3 to just precipitate all the aluminum?
Ten mL of concentrated H3PO4 (91.7% by mass, d=1.69g/mL) was accidentally poured into a beaker containing 20.0 g of NaOH. Not all the NaOH was consumed. How many grams of NaOH were left unreacted? The equation for the reaction is H3PO4(aq)+3OH(aq)3H2O+PO43(aq)
A sample of limestone weighing 1.005 g is dissolved in 75.00 mL of 0.2500 M hydrochloric acid. The following reaction occurs: CaCO3(s)+2 H+(aq)Ca2+(aq)+CO2(g)+H2O It is found that 19.26 mL of 0.150 M NaOH is required to titrate the excess HCI left after reaction with the limestone. What is the mass percent of CaCO3 in the limestone?
A sample of solid Eu(OH)3 was stirred in water at a certain temperature until the solution contained as much dissolved Eu(OH)3 as it could hold. A 650-mL sample of this solution was withdrawn and titrated with 1.33e-05 M HBr. It required 21 mL of the acid solution for neutralization.What is the solubility of Eu(OH)3 in water, at the experimental temperature, in grams of Eu(OH)3 per liter of solution? a) The solubility is 7.06e-10 g/L. b) The solubility is 8.72e-05 g/L. c) The solubility is 0.000262 g/L. d) The solubility is 2.91e-05 g/L. e) The solubility is 6.08e-06 g/L.
CHEMISTRY (Please write the complete solution legibly. No long explanation needed. Answer in 2 decimal places. Box the final answer.) Solve the following: a. Calculate the molarity of hydrochloric acid, HCl, in a solution if 25.00 mL of that solution required35.74 mL of 0.1522 M KOH for complete neutralization in a titration. (Answer: 0.2176 M) b. When aqueous solutions of Ba(NO3)2 and K2SO4 are mixed, a precipitate of BaSO4 results. Writethe molecular, ionic, and net ionic equation for this double displacement reaction. c. 8.50 g of copper (II) sulfate pentahydrate, CuSO4∙5H2O, is dissolved in 250 mL of solution. Whatis the molarity of this solution?
Sodium formate reacts with permanganate in neutral solution according to the equation CHO2 + MnO4 + H2O → MnO2(s) + CO2 + OH" (a) A 0.500 g sample containing sodium formate is treated with 50.00 mL of 0.0600 M MnO4 (an excess) in neutral solution, and the reaction given above is allowed to proceed to completion. The solution is filtered to remove the MnO2, acidified with H2SO4, and titrated with 30.00 mL of 0.1000 M H2C2O4. The MnO4- is reduced to Mn2+ and the oxalate oxidized to CO2. Calculate the percentage of NaCHO2 in the sample.
