Kephra,

  Does the ppm meter you sell at the SilverTron Store measure the conductivity?

Bobby
Yes, it is both an EC meter and ppm meter.

Water PH varies

I don't know if this has been mentioned before but.......

Distilled water is acidic because it absorbs carbon from the atmosphere.  You can drive out the extra carbon by boiling at a rolling boil for 15 minutes then sealing it while still steaming in an airtight container.  Use a glass or stainless steel pot to boil in.

The PH difference between boiled and not boiled is striking.

We use mason jars.  If the jar vacuum seals when it cools, (it usually does unless your canning flat is bad), the distilled water remain alkaline, (less dissolved carbon).

I learned this while researching how to make electrolyte for large Nickel Cadmium cells used in my solar system.

Hope this helps someone.

The solubility of CO2 decreases with temperature, so boiling would drive off most of it.  However, this is unnecessary when using sodium carbonate for electrolyte and its time consuming and uses up a lot of energy.

For reducing agents, there are lots of choices include, glucose, maltose, maltodextrin, cinnamon extract, other plant extracts, corn syrup (Karo), Tate & Lyles golden syrup etc.

The silver lungs guy tries to get you to buy his expensive reducing agent, but its just a carbohydrate like one of the above.

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 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...

Another thread that concerns the purity of silver rod:

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!!!

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

These are 20 ppm with 15mA run for 10 minutes, 0,2 grams malto, 0,4 ml electrolyte get around 200 mS EC
Left one stirred and heated after process, The right one heated before process and stirred without heating
Why i always get darker colour compare with other people sample and also has tyndall effect
Any idea?

That looks more like 50ppm.

i just make a new batch without reducer but the colour looks pale yellow and clear,  is it possible to get pale yellow without a reducer?

Yes, both heat and light will reduce silver.  Specifically blue and ultraviolet reduces silver but not red.  Fluorescent light and sunlight contain blue wavelengths. 
The silver will not be as stable because there is no stabilizer.  Also, it makes bigger particles.

Too much reducing agent is ok
but how if too much electrolyte? i cant get conclusion or any information about it, maybe i missed it
Can anyone please explain it, thank you
