Gold metal will not dissolve in either concentrated nitric acid or concentrated hydrochloric acid It will dissolve, however, in aqua regia, a mixture of the two concentrated acids. The products of the reaction are the AuCl4 ion and gaseous NO. Write a balanced equation for the dissolution of gold in aqua regia.
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?
A chemist dissolves a 1.497-g sample of a type of metal (an alloy of Sn, Pb, Sb, and Cu) in nitric acid, and metastannic acid, H2SnO3, is precipitated. She heats the precipitate to drive off the water, which leaves 0.4909 g of tin(IV) oxide. What was the percentage of [in in the original sample?
Sodium bicarbonate (baking soda), NaHCO3, can be purified by dissolving it in hot water (60 C), filtering to remove insoluble impurities, cooling to 0 C to precipitate solid NaHCO3, and then filtering to remove the solid, leaving soluble impurities in solution. Any NaHCO3 that remains in solution is not recovered. The solubility of NaHCO3 in hot water of 60 C is 164 g/L. Its solubility in cold water of 0 C is 69 g/L. What is the percent yield of NaHCO3 when ills purified by this method?
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?
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.
A sample weighing 9 g of BaCl2 is dissolved in 700 mL of water, when 50 mL of the sample is titrated with 30 mL of 0.5 N AgNO3 the percentage of chloride Cl- (A.wt = 35.5) in the sample is *
Potassium hydrogen phthalate, known as KHP (molar mass = 204.22 g/mol), can beobtained in high purity and is used to determine the concentration of solutions ofstrong bases by the reactionHP −(aq) + OH −(aq) → H2O(l) + P2 −(aq)If a typical titration experiment begins with approximately 0.5 g KHP and has a finalvolume of about 100 mL, what is an appropriate indicator to use?

A 0.7785 g sample containing hydrazine (N2H4, rocket fuel) was dissolved and diluted to 250.0 mL in a volumetric flask. A 25.00 mL aliquot was treated with 50.00 mL of 0.0313 M KBrO3, which reacts with hydrazine as follows: 2KBrO3 + 3N2H4 ---> 2 KBr(aq) +3 N2(g) +6H2O The solution was then acidified after adding additional Br-, which converted the excess BrO3- to Br2. BrO3- + 5Br- + 6H+ -----> 3Br2 + 3H2O The bromine was then reacted with excess I-. Br2 + 3I- -----> I3- + 2Br- The liberated I3- was then titrated with 0.1115 M thiosulfate, HS2O32-, requiring 10.76 mL to reach and endpoint. Calculate the weight percent hydrazine in the sample.

The vanadium in a sample of ore is converted to VO2+ . The VO2+ ion is subsequentlytitrated with MnO4- in acidic solution to form V(OH)4+ and manganese(II) ion. Theunbalanced 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 ofvanadium in the ore was 58.1 %, what was the mass of the ore sample? Hint: Balance the titration reaction by the oxidation states method.
