The phrase "acid acid" is not correct or usable in written English as it lacks clarity and context.
It could potentially be used in a scientific context, such as when discussing different types of acids or a specific compound that has "acid" in its name.
Example: "In the laboratory, we analyzed the properties of acid acid to determine its effects on the reaction."
Alternatives: "acidic compound" or "acid solution".

My impressions of the night were diffuse, many fixating on the shabby human carnival that had taken over the parking lot and the pavilion: freaks dangling from trees, skulking muppets muttering, "Acid, acid".
The Castalia Institute no longer exists and these days Millbrook has a different kind of research center, the Institute of Ecosystem Studies, with a director, Gene Liken, who studies a different kind of acid: acid rain.
The effects of different acids (oxalic acid, maleic acid, citric acid and sulfuric acid), acid concentration, reaction temperature and reaction time on the hemicelluloses hydrolysis were investigated.
It has been reported that ACV consists of acetic acid, flavonoids such as gallic acid, tyrosol catechin, epicatechin, benzoic acid, vaninilin, caftaric acid, coutaric acid, caffeic acid, acid and ferrulic acid These constituents have been reported to affect immune defence and oxidative responses18,33.
The kenaf fiber was treated at room temperature for 24 h, using two amino acids namely glutamic acid (acid) and lysine (base).
The acid acid-activated bentonite displayed also even higher color and chlorophyll removal than both the Tonsil and Maghnia standards, for similar bleaching earth amounts.
With respect to the latter process, we observed down-regulation of the enzymes CYP2C39 and ACSL3, which both utilize A-acid acid as substrate.
In FFA-CNB co-crystal, robust supramolecular acid-acid homosynthon was observed.
The majority of the compounds showed π-π stacking between the pyrimidine-pyrimidine, pyridine-pyridine and acid-acid moieties rather than acid-pyridine or acid-pyrimidine moieties.
It is also interesting to note that in all the compounds π-π stacking occurs between the pyrimidine-pyrimidine or pyridine-pyridine or acid-acid moieties rather than acid-pyrimidine/pyridine.
