What affect does AC have on a electrochemical Cell?

[Wayne]

Hi

I am trying to look at different slants to this question and I would like
some input from anyone out there who would like to.

One idea is that if an AC bias is applied to a cell (such as one with two
copper electrodes and de-ionised water) then Under AC an ion will move back
and forth proportional to the applied alternating field and always return to
the originating electrode. Therefore, AC will have no effect on say
whisker/dendrite formation.

What other affect happen unders AC?

Apart for the classic electrochemical factors that effect the growth of
dendrite, temperature, electrolytic constants and humidity, these other
point may need considering:

1. Brownian Movements

2. Particle Mass

3. Dipolar nature of ions

Heating, but in deionsed water the resistivity is high and so almost no current
flows --> heat effect is moderate (R*I*I).
On a chemical level, nothing noticeable happens since what is done is undone
1/50th of second later when the current reverse.

But when you submit DC cell to ultrasonic waves...you get in some cases metalic
dust suspensions :-) but this is another story.
