So, Loveall, help me out here. You extracted using the std process with 100g of material, then split the 900 or so mL of pulled solvent into two equal-sized batches, and added the specified amounts of citric?  I must be missing something about the volumes, only 0,095g made the solution neutral?

I guess i was stoned the day they discussed deprotonation, i don’t understand the general approach, though it sounds like you know what’s up.
