Find the concentration of Ca2+, in equilibrium with CaSO4(s) and 0.035 M SO4-2.
A solution contains 0.0330 M Pb2+and 0.0210 M Ag+. Can 99% of Pb2+be precipitated by chromate(CrO42-), without precipitating Ag+? What will the concentration of Pb2+be, when Ag2CrO4begins to precipitate?
If a solution containing 0.015 M each of bromide, chloride, iodide, and thiocyanate, is treated with Cu+, in what order will the anions precipitate?
