The PH difference between boiled and not boiled is striking.

The focus is: Getting the molarity of sodium carbonate in your solution correct. The MATH proves out what it will be. Your PH measuring method whatever it may be, will NOT be as accurate. The PH is important, sure, but if you are measuring correct amounts, measuring PH absolutely becomes irrelevant.
If I follow my own advise, Pure Distilled Water, Pure Sodium Carbonate(Anhydrous) all measured out correctly, and it comes back PH 8, or 9.3, etc, the PH measuring is in error.

If you really want to have fun. Boil the distilled water under a vacuum of say 0.1 ATM (cheapest vacuum pump). With a little time that will remove all those dissolved gases too ;D If you are good you can probably put the meter or calibrated probe part in the vacuum too since electronics does not care.

MY game is the minutia.
Nit-picking to perfection.
The Guides will tell you how to make repeatable high quality stuff EVERY time.
MY bag is splitting the hairs to get to the minimum amount of Reducer / Stabilizer per batch that results in perfect clarity, color, stability. I am MUCH further than just 2 months ago.

Sometimes when I forget about electrolyte mixture, This thread is reminding me how is done correctly. :-[
I wish I stumbled on it in my early days...

Thanks Kep...

Hi,
I have doups.
Only with the reducing ante can we avoid the batch being ionic silver, or is it necessary to add the reducing agent?
The definitive proof that it is really AGNP is that it must not taste like metal and the color must be light yellow, right?
Otherwise it is ionic silver?
Thank you!!!

Correct.

My first batch and it does not look good,
look darker than most people do i guess
add too many maltodextrin 6 times higher
will make a new one tomorrow for 20 ppm and do it step by step by the book
