Shocking revelations: a conductometric titration

Conductivity gives indirect evidence of the presence of ions in solution, and of their concentrations and even the ways in which water interacts with them. Eliminating as many variables as possible, we can see evidence of the ionic equation of neturalisation, which 14–16 year old students encounter in their chemistry lessons. This video and article describe a conductometric titration of barium hydroxide with sulfuric(VI) acid to show this and strengthen students’ mental models of particles reacting in solution.
