Setting the scene
The impact of water is increasingly significant in more advanced school studies of acids, bases and pH. This demonstration shows the dramatic effect on conductivity as water is added to concentrated (glacial) ethanoic acid.
Would you expect concentrated ethanoic acid to show significant conductivity?
Would you expect pure water to show any significant conductivity with a conductivity meter?
What might you expect to happen to the conductivity when water is added to concentrated ethanoic acid and why?
