calculate the Zn2+ concentration of a solution prepared by mixing 50.0mL of .0250 M Zn2+ with 50.0mL of .1M ammonia solution that was buffered to a pH of 6. Given the stepwise formation constants for Zn(NH3)4 complex are logKf1=2.18 , logKf2=4.43 , logKf3=6.74 , logKf4=8.70 and the pKb fo ammonia is 4.76.
