Kf of Ag(NH3)2+ = 1.7 X 107 answered 11/02/22, Ph.D. University Professor with 10+ years Tutoring Experience, AgBr(s) <==> Ag+(aq) + Br-(aq) Ksp = 5.0x10-13, Ag+(aq) + 2NH3(aq) <==> Ag(NH3)2+(aq) Kf = 1.7x107, _______________________________________________, AgBr(s) + 2NH3(aq) <==> Ag(NH3)2+ + Br-(aq) K = 8.5x10-6, AgBr(s) + 2NH3(aq) <==> Ag(NH3)2+ + Br-(aq), .5.300..0..Initial, -2x..+x+x.Change, ..5.30-2xx..x..Equilibrium, 8.5x10-6 = (x)(x) / 5.30 - 2x and assuming x is small relative to 5.30 we can neglect it in the denominator.
