Completing an electric circuit with salt water

  • #1
Howdy!

I would like to complete an electric circuit using salt water and two electrodes, however I don't want my electrodes to corrode or change the chemistry of the electrolyte (salt water), so I don't want electrolysis to take place. Is this possible?

I read in a published paper that electrolysis don't take place when using AC current and Cu or Zn as electrodes and in that case "the solution behaves much like resistance and the energy is wasted in heating of the solution." Does corrosion take place in this case? does any other chemical reaction take place?

The paper I referred to attached to the thread or from (http://goo.gl/hdzyBf [Broken])

Thank you,

What voltages and/or currents?

Exactly .. in the paper they used low power (tens of Volts and mAmps) .. I want to investigate this on high power (kiloWatts)
Do you think it will be different?

Depending upon current density (i/Aelectrode), it could be spectacular.

So for high alternating currents the solution wont behave as a resistor, electrolysis will take place and electrodes will corrode?
