A solution contains 0. 036 mol l-1 cu2+ and 0. 044 mol l-1 fe2+. A solution containing sulfide ions is added to selectively precipitate one of the metal ions from solution. At what concentration of sulfide ion will a precipitate begin to form? what is the identity of the precipitate? ksp (cus) = 1. 3 10—36, ksp (fes) = 6. 3 10—18
