How to Make a Citric Acid Solution
- 1). Purchase at least 1 lb. of citric acid crystals, sometimes sold as "Sour Salt," from your local gourmet food store. Boil 1 or 2 pints of distilled water for every pound of citric acid you plan to dissolve, depending on how strong or weak you want your solution.
- 2). Place the citric acid crystals in a non-metal pot. Remove your boiling water from heat and tip its container slightly to slowly introduce it to the acid crystals, stirring with a non-metal spoon while doing so. Filter the solution using filter paper (a coffee filter will do) to remove any non-dissolved solids.
- 3). Store your solution in an airtight container. According to an excerpt from "A Treatise on Beverages" by Charles Herman Sulz, citric acid solution is prone to developing fungus if exposed or otherwise left vulnerable to air or contaminants.
