i am trying to make colloidal gold from here
https://www.cgcsforum.org/index.php?topic=4588.msg41611#msg41611but i do not have sodium citrate, can i use make it with following method?
"You can make it. Sodium citrate is the salt of citric acid and sodium. Citric acid can often be found at health food stores or in Latin or Asian food aisles as sour salt. The sodium can be derived from baking soda.
Roughly, you'll want three parts baking soda to one part citric acid. Sodium citrate has three sodium ions for each citric acid ion, and each baking soda molecule has one atom of sodium. For example, if you want 10 grams of sodium citrate, you'll combine 30 grams of baking soda with 10 grams of citric acid in a small amount of water. You'll see bubbling as carbon dioxide escapes, and you'll end up with a bit more water that is also generated by the reaction. The resultant liquid should taste salty but not sour.""
thank you
