Adrian Dingle's Chemistry Pages
Chemistry Educator, Tutor & Author
Being an author is hard. It’s hard for many reasons and believe it or not, it’s not all about going to the beach to find yourself, staring out to sea for six weeks, and writing the guts of a NYT best seller. Some people think it is. Nor is it (in almost all cases), about [...]
Today I have submitted my 2013-14 AP Chemistry Syllabus/Audit (version 1 with more anticipated), and I thought it might be fun (and perhaps informative!) for me to document the process here. My thoughts on the original audit (and the latest one) are well documented, and I see no point in a detailed re-hashing all of that [...]
I have just about completed the first draft of the re-write of my AP chemistry materials for the new curriculum. Just for fun, I decided to do a Wordle word cloud for each of the six sets of notes for Units 1-6, that correspond to each of the College Board six, Big Ideas. Not sure [...]
I’m currently heavily into my AP material re-write for the new curriculum, and am encountering a number of LO’s that require me to re-think some things. One way I have been tackling some of the more obscure LO’s, is by adding additional Tasks to my notes. I thought that you might like to see a [...]
My recent conversation with Eric Scerri that spawned this post, was initially provoked by his article from the previous week in Scientific American. It got me thinking about an old AP exam question from 2006, that asked about the as yet undiscovered element 119. That question was incredibly easy in the grand scheme of things, [...]
Yeah, that’s an inelegant title to say the least, but behind it is an elegant piece of chemistry that is struggling to get recognition. Yesterday I had the enormous pleasure and privilege to chat with UCLA chemistry professor and venerable author and expert on the periodic table, Eric Scerri. Eric and I chatted about a [...]
More random facts. 1. Organic amines like methylamine, CH3NH2, are weak bases since the lone pair on the N atom can accept H+. 2. Nickel (II) salts are green. 3. Positive Ecell values go with negative Delta G values and very large K values. 4. When [H+] in solution is < [OH-] the solution is [...]
Random facts. 1. The speed of a chemical reaction is not related to the equilibrium position. 2. Hydrogen bonding is an INTERmolecular force, not an INTRAmolecular bond. 3. Electrolysis is only necessary when a reaction is non-spontaneous with a positive Delta G. 4. Rutherford’s Gold Foil Experiment produced evidence of a dense, positively charged nucleus. [...]
It’s that time of year again, AP review, and whilst Atlanta in the spring tends to feel a long way removed from Christmas, this really is the most wonderful time of the year for any student preparing themselves for the AP Chemistry exam in the first week of May. I say that mainly because the [...]
Well, I guess if you’ve made it this far you already know that. A new logo, a new look and new content announce the new, Adrian Dingle’s Chemistry Pages! As is the norm with moves and changes of this magnitude, there is going to be a significant settling-in period, and to be honest, it will [...]
