In this video I go over an example problem of how to find the concentration of an ion left over after equilibrium was reached for the formation of a complex ion.
CORRECTION: When I set up the expression for Kf to solve for [Cu2+], I forgot the power of 4 for the [NH3]. However, I did the calculation correctly when I prepared for this video. So, the answer I got is actually the correct answer because when I calculated it before I made the video, I actually did take into account the [NH3] being raised to the 4th power.
