Chapter 15, Problem 95(choose chapter or problem)
Many metal ions form insoluble sulfide compounds when a solution of the metal ion is treated with hydrogen sulfide gas. For example, nickel(II) precipitates nearly quantitatively as NiS when H2S gas is bubbled through a nickel ion solution. How many milliliters of gaseous H2S at STP are needed to precipitate all the nickel ion present in 10. mL of 0.050 M NiCl2 solution?
