Hello.
Liquids and liquid electrolytes of many compositions have more or less electrical conductivity.
Is the conductivity preserved if the electrolyte freezes ? -Say a simple solution of sodium chloride-

 

I don't know about other electrolytes (I'd have to go dig up my old chemistry books), but salt water doesn't usually freeze; the ions recombine out of the solution and the water freezes, while the salt forms a strong brine at the bottom of the container holding the solution, until all the water is frozen and you just have salt crystals at the bottom. So, if I'm correctly recalling something I haven't studied in 10 years, the electrolyte will not have conductivity, because the components separate out.

Someone may want to double-check that; I'd do an experiment, but I'm not sure my freezer can overcome the freezing point depression of high-salinity water.

 

All Chemical-Reactions vary in Speed vs Temperature.

Is the conductivity preserved if the electrolyte freezes ?

No. The electrical conductivity changes upon freezing and ultimately depends on the structure of the ice. So it can be different depending on pressure, the concentration of the electrolytes, and so on.

The original solution conductivity should return upon melting and re-dissolution of any precipitated electrolytes.
