I fail to see the significance of the water pH or EIS pH. Dose it has any health consequence, considering the minute amounts one usually takes?

Be aware that pH (base 10) is a log scale, so figuring what the initial pH contributed to the final is not trivial. For instance, a pH of 9 is 10 times more alkaline than a pH of 8, and a pH of 10 is 100 times more.

Like not getting a higher pH in homemade EIS. If you know the pH of the DW before making EIS, and it is near 7; then a resultant EIS that is not much higher that 7 might give a clue that it isn't good EIS.

I make mine in a gallon sun tea jug with a screw on top and the only way it is exposed to the air is what air could get in around the silver strips that fit fairly tight through slots cut in the lid. Of course if you turned it upside down it would leak liquid. Dave On Mon, Jul 8, 2013 at 10:04 AM, Joe Huard <joe.hu...@primus.ca> wrote: Distilled water should be around pH 7 when freshly made. However, if left sitting around exposed to air, it can go down to pH 5.5. I read that nitrogen which is 78% of the air reacts with the DW and creates nitric acid. If you measure the pH of your DW right before you make EIS and right after making EIS, you should get a higher pH. Joe H. On 08/07/2013 12:39 PM, Da Darrin wrote: Strange! My meter or the best test strips I could find never went over 6.8 no matter how fresh or old my solution was.

Sample 1. Tested within 24 hours after production and pH read off the scale on the alkaline. Sample 2. Tested after it had been in storage for a week or so read >7.0 Note: Whilst I am unable to locate the exact numbers on the above, I do know they were greater than base 7.0 because I had those two samples tested specifically for pH to varify the findings of the following. Several years prior to the above I had several other samples {from different batches and storage time frames} laboratory analysed of my EIS and one of those tests included pH and ALL were between 7.4 and 7.8 My conclusion going on all the above tests...pH is sky high immediately after cessation of the brewing process but drops over time to steady at >7.0, none were below 7.0 or acidic. That is expected. Ionic silver is a combination of silver oxide and silver hydroxide. Silver hydroxide is alkaline. Over time the ionic silver tends to form colloidal silver, thus the ph should go down toward 7. Now if exposed to air for sufficient time, the ionic silver will eventually react with CO2 in the air forming silver carbonate, a salt, and eventually one could expect the pH to go below 7, as carbonic acid is formed and there is no silver hydroxide left to neutralize it. I had samples 1 and 2 tested by water people {people who monitor swimming pools} as I don't trust those Litmus paper thingo's, or those pH meters. I think most of these people use the pH meters themselves. If done properly, the meters can be quite accurate. Marshall ________________________________________ No virus found in this message.
