WebJun 17, 2024 · If I'm not wrong that should be a 10% solution (in weight) and about 2.5M. From this resource the electrical conductivity should be about 309 mS/cm, so 3.2 Ohm×cm; this seems consistent given that electrolysis uses a lot of current. However with the highly non-scientific method of dipping the DVM probes in the solution I see more than 20 kOhm ...
