Before it was banned in the 1970s due it its non-selective toxicity, thallium (1) sulfate, TI2SO4 (s), was the active ingredient in some pesticides. A chemist measured 100.0 mL of a solution of thallium (1) sulfate and added excess aqueous potassium iodide to precipitate yellow thallium (I) iodide, TII (s). The mass of the dry precipitate was 2.45 g. Find the molar concentration of the thallium (I) sulfate solution. M(TII) = 331.3 g/mol %3D Tl2SO4 (aq) + 2KI (aq) → K2SO4 (aq) + 2TII (s)

Some wastewater stream contains 0.015 M Hg22+. Some chemical engineer decides to remove it by precipitating it as Hg2CO3(s). He mixes 100.00 ml of the wasterwater with 100.00 ml of a 2.00 M solution of Na2CO3 and filters the result to remove the solid. How much residual Hg22+ should he expect to find still in the water? (Hint: it should not be 0) Ksp of. Hg2CO3 = 9.0 x 10-15. Also keep in mind that Hg+ is the only ion that exists in solutions as a dimer, i.e. Hg22+, not 2 Hg+ (Hg2CO3→ Hg22+ + CO32-)

Sodium nitrate contains 0.3% iodine in the form of calcium iodate, Ca(IO3)2. After the sodium nitrate in the niter is dissolved and recrystallized, the remaining solution contains 9 g/Lsodium iodate, NaIO3(aq). The NaIO3 is converted to iodine when it reactswith sulfur dioxide and water.2NaIO3 + 5SO2 + 4H2O → Na2SO4 + 4H2SO4 + I2a. How many liters of sodium iodate solution that contains 9 g of NaIO3 perliter would be necessary to form 127.23 kg of iodine, I2?
