Solving a chemistry problem
8. Is it possible to precipitate Ni2+ ions from a solution of K2[Ni(CN)4] with a volume of 1 liter and C = 0.1 mol/liter containing 0.2 mol KCN (a = 80%) if 10-4 mol sulfide is added ammonium? At what minimum concentration of ammonium sulfide will a precipitate begin to form? (PR(NiS)=2*10-28).
