Question is, how do I recover the silver that is plating out the turkey baster I am using to measure the CS I take am & pm? It turning a really pretty silvery grey!

Some silver will plate out on the negative electrode. Using a silver negative electrode allows you to recover the plated out silver for use. - Steve N From: David AuBuchon [mailto:[email protected]] Sent: Wednesday, September 08, 2010 08:20 PM To: [email protected] <[email protected]> Subject: EXTERNAL:Re: CS>Does the cathode need to be silver? Correct me if I am wrong, but absolutely NOTHING physically comes off of the negative terminal during production, right? The only thing that comes off would be electrons reacting with water molecules or incoming silver ions or a few amount of contaminant cations. I'm wondering if the ideal gen has a lot of surface area on cathode also. If so, copper would be preferable so you don't pay for all that extra silver. Hey, could that also make a gen that doubles as a colloidal copper setup? What do people use colloidal copper for anyway? ~David On Wed, Sep 8, 2010 at 6:01 PM, Dan Nave <[email protected]> wrote: The cathode (in this case the negative terminal) can be copper if you are not polarity switching. The anode (in this case the positive terminal) must be silver. You can see I don't agree with cking, as usual...
