Can you use Sulfuric Acid and Potassium Hydroxide to do a spice extraction

Sulfuric acid works fine. It is quite corrosive, which is why most people stick to vinegar or phosphoric acid.

Potassium Hydroxide will work as a base just as well as Sodium Hydroxide.

Why do people especially since it so hard now to get Lye without question or visit do people not use Potassium both available in large quantities at your local pet shop as Ph - + for Aquariums ???

I'm not sure...that is a good question. Most teks call for sodium hydroxide so that is what people look for.... Posassium Hydroxide seems like it would work just as well. It can raise the pH of water to 14 just like NaOH....maybe more is needed? I don't know.

Any chemist friendly members wish to comment?

pH Up is nowhere near pure KOH or people would be frying the shit out of their fish all across the country.

pure KOH and pure NaOH will work equally well. the problem is obtaining them clean without aldulterants. like color additives stuff like this. thats why i would be careful with what you buy if its pure white pellets and thats all thats on the ingredient list then its safe and will work fine.
