Top of the morning Wayne, Bottom line is that you CAN measure the conductivity of the silver solution.
Everything else is a calculation based on the known properties of chemicals and electricity. But, we don't always know exactly what we have in our solution either... Dan PS. You can't compare tomatoes and colloidal silver... > -----Original Message----- > From: Wayne Fugitt [mailto:[email protected]] > Sent: Tuesday, August 19, 2008 12:43 AM > To: [email protected] > Subject: CS>Ion Drift Interesting > > Morning Marshall, > > At 10:40 AM 8/18/2008, you wrote: > >He is saying that the drift veloicty of sodium and chlorine ions is > >twice the drift velocity of silver and hydroxide ions.
