A solution is prepared such that the initial concentration of Cd2+ is 3.80×10-2 M and the initial concentration of Br is 7.50x10-2 M. Cd2+ and Br are allowed to react as shown below to establish equilibrium with the complex CdBr42-. equilibrium concentration of the complex CdBr42- is determined to be 2.9×10-3 M. Cd2* (aq) + 4 Br (aq) = CdBr42- (aq) %3D What is the formation constant, Kf, for this complex?
