You may want to reference (Pages 821 - 825) Section 17.8 whilecompleting this problem. You mix a 120.0 −mL − m L sample of asolution that is 0.0123 M M in NiCl2 N i C l 2 with a 185.0 −mL − mL sample of a solution that is 0.300 M M in NH3 N H 3 .
After the solution reaches equilibrium, what concentration ofNi2+(aq)Ni2+(aq) remains? The value of KfKf forNi(NH3)62+Ni(NH3)62+ is 2.0×1082.0×108.
Express the concentration to two significant figures and includethe appropriate units.
