Using Citric Acid in DIY

[ChelsB]

And the pH pen needs to be submerged for 30 seconds to get an accurate read? I assumed it would be immediate?

 

[ChelsB]

Do they mean coffee filter paper or is a standard paper towel sufficient?

Use distilled water. The pH of tap water can vary depending on location.
I would do an initial calibration an then check it in distilled water from time to time. The stability will depend on the quality of the instrument.
The reason it needs time is that it probably takes multiple tests and averages them.
When they tell you to use filter paper, they're assuming you are in a lab. I would use any clean and lint-free paper.

Why does the meter keep reverting back to my first calibration (6.86)? This was using the 9.18 powder ...huh???

Maybe 6.86 is its "Neutral State".

And then the Meter Reads whatever you are testing and calculates if it is More Acid or Alkaline then the Calibrated 6.86ph.

devices of that type usually require that the calibration procedure is completed in a relatively short time, exactly following their procedure. How many steps in the process.

BTW - I have a ph Meter somewhere in some drawer or closet.

And as I recall on mine, It Only reads ph when it is in a liquid and the button is being pushed. Once I take it out of the Solution, it reverts to like 3 Bars (---).

Maybe that is what yours is doing?

Once it is Out of the Liquid it reverts to the Calibrated Value?

There were 3 different levels of pH powder for calibration. I followed the steps exactly. But this is my first time using a pH meter

Aha! That could very well be what is going on! Excellent advice!

Does the CA/PG mix ever fully mix together/dissolve? Mine keeps separating

 

[ChelsB]

Is CA harmful to plastic? I spilled a bunch on my scale. Just curious if I hadn’t cleaned it immediately if the CA would start to eat at the plastic?

"necessary", probably not, but I dont know how to get repeatable results otherwise, unless you are using the exact same recipe every time and only changing the acid variable as you experiment.

do you think using the ph meter would also work in the same ways if you were using benzoic acid...could you simply make a benzoic base and add it to your juice till you reach a certain ph.

 

[Equality 7-2521]

If you can trust the Liggett researchers (cited above), the nic salts vs. the freebase nicotine boils down to slower absorption in the salts form. I would think that this is exactly the opposite effect to what is desired by vapers who are using vaping to stay off the smokies. Faster absorption is closer to the effect of smoking.

I keep running into this same information...nic salts allow you to vape higher levels of nic comfortablly, but that is absorbs slower, but then I think on Nic River's website they say nic salts cross the brain blood barrier better than freebase...sure would like some defenitive answers on this.

Yes, as far as a ph meter is concerned, an acid is an acid.

Not likely. I keep mine in plastic.

Yes, but it takes some work. Heat will also help along with lots of stirring.

Spot on.....

Thanks so much, you’re an excellent resource!

I figured it was a stretch, but was curious nonetheless
