Suggest a method for separating a precipitate consisting of a mixture of solid CuS and solid Cu(OH)2.
Distinguish between the terms slightly soluble and weak. electrolyte.
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?
Calculate the solubility in grams per 100 mL of BaF2 in a 0.10 M BaCl2 solution.
1. 0.646 g of sample containing BaCl2.2H2O (244.26 g/mol) was dissolved and enoughpotassium chromate was added. After filtering, the precipitate was dissolved in acid andenough KI was added and titrated with thiosulfate. Since 48.7 mL of 0.137 M thiosulfateis used for this, what is the percentage of BaCl2.2H2O in the sample?K2Cr2O7 + 7H2SO4 + 6KI  4K2SO4 + Cr2(SO4)3 + 7H2O + 3I2
Which anion or anions are not present in a solutionthat forms no precipitate upon addition of BaCl2 (aq)?
A saturated solution of magnesium hydroxide is prepared and the excess solid magneisum hydorixed is allowed to settle. A 25.0 mL aliquot of the saturated solution is withdrawn and transfered to a flask, two drops of inficator are added. A 0.00053 M HCL is dispensed from a buret into a solution. The solution changes color after the addition of 13.2 mL. What is the molar concentration of the hydroxide ion in the saturated solution?
Question 22 of 30 Submit A 185.0 mL sample of 1.200 M Pb(NO3)2 is mixed with 123.50 mL of 1.500 M NaCI, and the PbCl, precipitate is filtered from the solution. Then 200.0 mL of 3.000 M NaBr is added to the remaining solution, and the PbBr, precipitate is also collected and dried. What is the mass (in grams) of the PbBr, precipitate, assuming the yield in each precipitation step is 100%? 1 4 6. C 7 +/- x 10 0 Tap here or pull up for additional resources LO 00
It is desired to neutralize a solution X that contains a mixture of potassium chromate and hydrochloric acid. Titration of 11.3 mL X with 0.104 M silver nitraterequired 78.6 mL of the latter. The resulting precipitate, containing a mixture of Ag2CrO4 and AgCl, was dried and found to weigh 1.250 g. How much 0.107 M sodium hydroxide should be used to neutralize 11.3 mL solution X?
Several alloys that contained only silver and copper were analyzed by dissolving weighed quantities in nitric acid, introducing an excess of iodate ions, and bringing the filtered mixture of silver iodate and copper (II) iodate to constant mass.
