Acids, bases, resources and more
Discussions from the magazine, blog, website and social media
Comments from our readers on how to smooth the transition from school to higher education, suggestions on teaching acids and bases and different viewpoints on what makes a good teaching resource.
In our CPD article, Morag Easson explains how to neutralise student difficulties when learning about acids and bases. Bob Worley added his own suggestions online:
The presence of ions in solutions and solids is indicated by the conductivity of an electric current. This aspect of chemistry is shunted into electrolysis now with no mention of the conductivity of solutions.
In my microchemistry workshops I introduce the CLEAPSS conductivity indicator. It illustrates that pure water conducts an electric current very poorly (no light on the LED) but tap water conducts better as the LED lights up.
