During the extraction of many alkaloids, you lower the pH in order to protonate the compound, making it polar and water soluble. With Mescaline, you must precipitate it as a salt.
What I don't understand, is how can you figure out the mole ratio between the Mescaline and the conjugate base of the acid (for example acetate). My understanding is you'd have to figure out the charge of the protonated mescaline. How? Thanks
The reason is not so I can ionize all of the mescaline. I want to know this so I can calculate the molar mass of the mescaline salt. That way I can take the weight I have of product, and calculate (using the molar mass) the weight equivalence of freebase mescaline, for dosage purposes. Also, it's just interesting knowledge that I'd like to know.
