Here’s a common question that I was asked once again today; Adrian, why do some of your materials point to equilibrium problems that contain the need for quadratic equations, when we know that type of math will not be tested on the AP chemistry exam? In other...

All things bright & beautiful, all creatures great and small. Remember that hymn? We often talk about remembering the little things, well here’s a lesson in remembering the big things as well! This post started life with an entirely different title. It was...
Feb 27, 2016 | 2013-14 Curriculum, Big Idea 6, Equilibrium |
We’ve lived through the nonsense of the inclusion of PES in the new AP Chemistry curriculum. Many think the exclusion of quantum numbers, stinks. Some people HATE the removal of colligative properties from the course. For me, these (and other things) provoke...
Feb 24, 2016 | AP, Big Idea 6, Equilibrium, Writing Good Answers |
Here’s the latest in the ‘writing good answers’ series, Writing good answers to AP Equilibrium problems. This post only deals with aspects of equilibria such as Kc, Kp, Ksp and Le Châtelier’s Principle – I’ll deal with Acid-Base...

Following the mention of the cobalt(II) complex ion system in this post from a couple of days ago, here’s a 30 second video clip of Le Châtelier’s principle in action in the same (with The Smiths). The equilibrium that is set up is this, [Co(H2O)6]2+(aq) +...

When it comes to water in equilibrium mixtures and Le Châtelier’s principle, things can be confusing, so let’s try to take some of the mystery out of this. When reading EK6B1a in the AP Chemistry CED, one finds this; The final few words are what I care...
