Balance the reaction. Be sure to enter a "1" if a "1" is assumed. Mg(OH) 2 (s) + HCl (aq) --> MgCl 2 (aq) + H 2O (l).
A student performed a redox titration of 10 mL samples of acidified tin(II) chloride solution, with standardized KMnO4(aq) as the titrant in a burette. Calculate the concentration of the acidified tin(II) chloride solution if 17.4 mL of 0.100 mol/L of standard potassium permanganate solution was used. Select one: O a. 0.435 mol/L b. 0.174 mol/L C. 0.0696 mol/L O d. 0.144 mol/L
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-)

Many salts of Pb2+ are sparingly soluble, and the difference in their solubility can be used to separate anions from solution.A solution is 0.0151 M in both Br– and SO42–. A 0.257 M solution of lead(II) nitrate is slowly added to it with a buret.The (pick one: Br^- or SO_4^2-) anion will precipitate from the solution first.(Ksp for PbBr2 = 6.60 ×× 10–6; Ksp for PbSO4 = 2.53 ×× 10–8) What is the concentration in the solution of the first anion when the second one starts to precipitate at 25°C? ___ M
