Re: Can A Salt-Water Fog or Mist Conduct Electricity?

Excellent and very interesting question!

The answer is "sort of".  What a salt water mist or fog consists of is a 
bunch of droplets of salt solution surrounded by air.  The droplets will 
conduct electricity, but the air acts as a very good insulator.  To get 
the fog to conduct, you'd have to apply a very high voltage (kilovolts +) 
from one side of the fog to the other.  What the fog is is a nonlinear 
electrical resistance, where at low voltage the fog appears to be an 
insulator, but at high voltage the fog will conduct, albeit with a very 
high resistivity. So there's our answer.

Regarding an experiment, there's no safe way to do the conductance 
experiment.  So PLEASE don't try to rig up something on your own--you 
could get electrocuted.

Thank you for a wonderful question.
