We are given a solution made of 0.0200 M Cu(NO3)2 and 0.500 M NH3 and its product Cu(NH3)42+ and asked to determine the concentrations of Cu 2+, NH3, and Cu(NH3)42+ at equilibrium, given the formation constant, Kf, of Cu(NH3)42+ that is 1.70 x 1013.
The complex ion Cu(NH3)42+ is formed in a solution made of 0.0200M Cu(NO 3)2 and 0.500M NH3. What are the concentrations of Cu 2+, NH3, and Cu(NH3)42+ at equilibrium? The formation constant, Kf, of Cu(NH3)42+ is 1.70 x 1013.
