I know that electric conductivity of metallic conductors increases with decrease in its absolute temperature(kelvin) . But is it the same for electrolytes such as water. Is cold water a better or worse conductor of electricity than warm water at same pressure and concentration.

Pure water is a terrible conductor.

Adding more salt increases conductivity.

Increasing temp will increase conductivity (in general) there might be some exceptions (depending on ions and solvent and the exact temp window).


Look at the second table on page number "14-16" for the seawater example here...
