Show that the Fe^2+ cation is a Group lll cation that will NOT precipitate out of...
A mixture contains 1.0 x 10-3 M Cu+2 and Fe+2 cations, and is saturated with .10 M H2S. Determine the pH where CuS precipitates, but FeS does not precipitate. Ksp for CuS = 4.0 x 10-36 and Ksp for FeS = 4.0 x 10-17
Please show all work. What is the pH of a saturated solution of Fe(OH)2? For Fe(OH)2, Ksp-8.0 × 10-16. 5.23 0 4.93 8.77 9.10/ 7.00

Above what Fe2 concentration will Fe(OH)2 precipitate from a buffer solution that has a pH of 8.62? The Ksp of Fe(OH)2 is 4.87×10-17.
Above what Fe2+ concentration will Fe(OH)2 precipitate from a buffer solution that has a pH of 8.14 ? The ?sp of Fe(OH)2 is 4.87×10−17.
Above what Fe2+ concentration will Fe(OH)2 precipitate from a buffer solution that has a pH of 8.57 ? The ?sp of Fe(OH)2 is 4.87×10−17.
Above what Fe2+ concentration will Fe(OH)2 precipitate from a buffer solution that has a pH of 8.60? The Ksp of Fe(OH)2 is 4.87 x 10^-17.
When C_r.co_3 = 10^-4 M and Fe^2+ = 2 times 10^-4, at what pH will FeCO_3(s) begin to precipitate as pH is increased? At what pH will Fe(OH)_2(s) begin to precipitate? The temperature = 25 degree C.
