E) In anoxic conditions (e.g. Ен= -0.3 V and pH=8) trace metals form very insoluble sulfides. Would it make sense to treat water to anoxic conditions to eliminate dissolved Hg? 1. What is the balance of sulfates/sulfides species? 2. Make a Pourbaix diagram for sulfate/sulfide species. 3. What other minerals can precipitate? (Hint: use the concentration of sulfides computed in the previous step, recompile the matrix using S²- and without e¯ and check for precipitation Hg + S minerals)

just Name and Balanced Net Ionic Equation for Precipitation:
A scientist wants to selectively precipitate silver from a solution of silver and copper. They propose using a solution of NaBr: AgBr Ksp = 5.4x10-13 CuBr Ksp = 6.3x10-9 Will the scientist achieve their goal using a NaBr solution? A.) No, because they will both precipitate at the same time. B.) Yes, because the ksp values are significantly different. C.) No, because AgBr has a larger Ksp. D.) Yes, because AgBr has a larger Ksp.
