Hi all,
Looking for advice from the chemists here.
I currently buy a mixed acid concrete etcher, which it's chemical make-up is not too specific as to percentages, but they are listed as 1. Water 2. Phosphoric acid 3. Nitric Acid.
This chem is fairly expensive, and I currently use it for small jobs I feel it is more effective than poorman's nitric.
I have a question about the use of this as AR. The wiki for phosphoric says when NaCL is added to Phosphoric, a salt is formed, as well as HCL. I wonder if the percentage is enough to be the 4:1 ratio recommended for AR solutions. If this were possible, it may be useful for easily stored, available AR. I had a hard time finding HCL for a while, and Nitric is a hard one too. Maybe this process could help someone, if it is plausible.
