Hi Dee, Sorry; I didn't do a very good job of generalizing the whole idea. Here's what I suspect just might be happening in this particular case; when you make your distilled water perhaps some air becomes entrained - not hard to do when you boil water. As this water cools, there may be a tendency for this entrained air to come out of solution and the microscopic bubbles could reflect just like any other particle giving you the Tyndall scatter. Try letting the distilled water sit for a while, meaning hours or a day. See if you get bubbles forming on the container sides. The conductivity will increase a tiny bit due to the absorption of CO2 from the air over that time forming H2CO3, carbonic acid. As a side note, distilled water from the store has sometimes had hydrogen peroxide added to it, H2O2, and the extra O will come out as above, leaving behind - H2O!~ tricky, huh? Why do they do it? Perhaps some added insurance against infection? Who can say?
