Today I covered two concepts that are arguably the most difficult topics students have in the solubility unit. Complex ion equilibria involve more than one equilibrium expression and tend to take multiple steps to calculate. It is VITAL for the complex ion problems that you get plenty of practice. You need to be able to perform problems 24-46 on the problem set for next week's quiz and you will definitely be responsible for these problems on the exam. Remember that all the problems posted on Carmen are taken from old exams, so this is the best way for you to prepare for the exam.
In addition to the complex ion problem, I covered the equilibrium expressions that allow us to analyze the separation between the Group II and Group III cations. These questions have definitely worked their way into the list of my favorites to ask on exams as they contain concepts learned from multiple sections of this course as well as 122. After today's lecture you should be able to handle questions 72-84 in the homework set and they will definitely show up on the quiz as well.
I hope everyone has a great weekend and I will see you in class on Monday :)
