You're very welcome. I recall that as a kid I once used a large 1.5- volt dry cell and a pair of carbon electrodes (from 2 old dead flashlight batteries) and electrolyzed some salt water. I could definitely detect the faint odor of chlorine at the anode The water around the negative cathode also becomes alkaline from the production of hydroxyl ions. This is observable by seeing litmus paper turn blue. If I can be of any further help with chemistry in the future, please feel free to get in touch. Can't guarantee anything, but I'll sure try (l'm a retired chemistry professor at KSU). ; - ) JimCo
