Hi Folks, First time poster here. I'm making up a special herbs and spices blend in a bucket of water and I'm keen to work out the potassium in it when it gets soupy. Any ideas? cheers from south australia

That would be a chemistry test that involves 1 large test tube and rack, chlorine to add to the liquid to precipitate out the Potassium, an accurate scale, filter paper and funnel (to collect the KCl precipitate and to dry it on) and a calculator to do the math.
Many commercial labs will do a Potassium test for you (here they cost between 25 and 50 dollars for the singular test).
