A Conversation for Alkanols

Sorry about the double post there.

I have to say I actually support the A level stance there I'm afraid because you *must* get used to doing your calculations in mol dm-3. Besides this makes teaching and assessment much easier along with reducing confustion amongst the students smiley - smiley

Use of other concentration terms is pretty much restricted to the use of solutions of approximate concentration for non-quantitative uses such as a wash solvent in a reaction work up or a quench to stop a reaction. Here no accuracy is needed whereas for a titration for example you need accurate molarities where you certainly will work in mol dm-3.

I quite agree about using S.I. units, they seem to be a lot more starightforward, and after using them for two years at A-Level, it was a bit confusing to adapt to different units (although it all made sense once you juggled them around a bit). But oh how we dreaded those long titration questions on the exams!

The only way of "reducing *confustion* amongst the students" is to make sure they take regular baths. smiley - winkeye

Actually "reducing confustion" was a seminal paper by Hoffmann in 1923 - a landmark paper in Organic chemistry
