+VE=Anode=O bubbles
Whichever plate arangement has your negative lead connected is the one producing H, If you reverse it then the other set of plates is now producing H. If you have more surface area on one set of plates than the other, that could account for more bubbles when reversing polarity.
When I was doing tabletop intro experiments I had one setup that just produced H because the anode was just turning dark and not releasing any O.
I wonder if there is a formula that can be used to calculate the distribution of volts/amps across the surface area of the plates so you would know what effect surface area has on producing gas...Statistics: Posted by hypersoniq — Sat Jun 14, 2008 4:10 pm
