    The resistance of salt water is dependant of the amount of salt in it.
The more salt, the lower the resistance, the less the higher.  I found that
salt water was an easy method of controlling resistances, or deriving exact
values.  The problem is that the electrodes will corrode, and if it's a DC
current it will be the negative terminal that dissolves, and the positive
that accumulates the oxidized metal.  Eventually the resistance of corrosion
will increase as it  builds up on the positive electrode.  The safety hazard
that it presents is caused by the fact the water molecules seperate into
their independent components Hydrogen, and Oxygen, and over a period of time
the gases build up.  It's not very safe to have around large sparks when it
can explode.
