What’s the (end) point?
While it is not explicitly mentioned in the curriculum, conductivity is a useful technique for following the progress of quite a few reactions, especially neutralisation reactions. It can also help illustrate the concept of ion mobility.
Conductivity flasks are generally expensive but this version uses a simple, home made substitute that, despite not being as accurate as one bought for the purpose will get perfectly usable results for the cost of a few pence.
