This chemistry video tutorial provides a basic introduction into complex ion equilibria. The first problem asks you to write the equations for the stepwise formation of Ag[NH3]+ and Ag[NH3]2+. It also asks you to calculate the overall formation constant value from the first two stepwise formation constants. Finally, it asks you to determine the equilibrium concentration of all species in the solution.
