Re: Potassium Oxalate recipe



Eric, wow, that was fast - thanks!

I wanted the recipe in metric because of the recipes I've found didn't stipulate US or UK gallons.

Thanks again.

John, 2 lbs of Pot Carb with 1.75 lbs to make 1 gallon of water. 1 lbs = 457
g and 1 gallon = 3.8 l ( top of my head but close enough as it is just POT
OX).

Mix you Pot Card into cool distilled water; about 1/2 your total volume.
SLOWLY add your Ox Acid as it WILL BUBBLE!!!!. Add to completion and top
off with water to make final volume.

Hi list

Does anyone have a recipe for potassium oxalate (as a Pt/Pd dev) using
potassium carbonate and oxalic acid in metric units.

Thanks
