An acidic solution is 0.01 M in Mg2+, Cu2+, and Fe2+. The pH of the solution is adjusted by adding NaOH. What is the maximum pH that removes only the Cu2+? Mg(OH)2(s) ↔ Mg2+(aq) + 2OH–(aq) Ksp = 6.3 x 10–10 Fe(OH)2(s) ↔ Fe2+(aq) + 2OH–(aq) Ksp = 4.1 x 10–15 Cu(OH)2(s) ↔ Cu2+(aq) + 2OH–(aq) Ksp = 2.2 x 10–20

stoichiometric coefficent to be in front of the variable in
question as well as an exponent, where as some only require the
coefficient as an exponent. what sets these two types apart? Here

Determine the pH increase of a solution after 0.10 mol of NaOH is added to 1.00 L of a solution containing 0.15 M HC2H3O2 and 0.20 M NaC2H3O2. If this same amount of NaOH was added to 1.00 L of pure water then what would be the pH increase of the resulting solution? Compare these two values. pH increase in buffer: ? pH increase in pure water: ?

Map pling A solution containing a mixture of metal cations was treated with dilute HCl and no precipitate formed. Next, H2S was bubbled through the acidic solution. A precipitate formed and was filtered off. Then, the pH was raised to about 8 and H2S was again bubbled through the solution. A precipitate again formed and was filtered off. Finally, the solution was treated with a sodium carbonate solution, which resulted in no precipitation. Which metal ions were definitely present, which...
