Hello, I looked at some mini a\b teks, and i find they say we should get water at a ph of 2-3 using something like vinegar. If someone's vinegar read 2.6 on the meter, how about using pure vinegar?

Thanks for reading

pH doesn't have to be so extrem (acid and base) for a mini A/B cause you don't need to lyse cells like when you work with vegetal material during an extraction.

You don't need to go that low. pH=5 is good because then, 99,9% of DMT is in salt form (check this to know how i know).
When you base, pH=12 is what you want.

To answer to you, you can use pure vinegar (which is 95% water +5% acetic acid) but it's not needed. And the more acid you use, the more base you will have to ad to neutralize it.

I use pure vinegar and it works. I do it to get to ph 2-3. It's 95% water anyway. It may not be necessary though, as DansMaTete says, so it would be cheaper not to.

I've never had a problem getting ph high enough after though. That lye is some pretty strong stuff.
