My take is, pure DI water conducts no electricity since there are no impurities, whether acidic or alkaline. My high school physics goes back a long way, but ionic means there are free electrons? This means there is potential for current flow, i.e. conductivity. So it shouldn't matter whether a solution is acidic or alkaline, either one should conduct providing a reading on a conductivity (TDS) meter? Perhaps you could run this question by one of the highly intelligent (and paid) professors at your university!

Ionic solutions are the charged particles (like mixing calcium chloride in water would form Ca+ and Cl-) and applying a voltage in the solution could cause the positive ones to go to negative terminal and vice versa. I can't recall whether there would be any free electrons. The hottest topic right now in Canreef with all the ionic balance and stuffs
We already have atleast "one" highly intelligent chemist in this forum isn't it?
