QUESTION 1
A solution is prepared such that the initial concentration of Cd2+ is 3.80x10-2 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.The
equilibrium concentration of the complex CdBr42- is determined to be 2.9x10-3 M.
Cd2+ (aq) + 4 Br (aq) = CdBr42- (aq)
%3D
