WebApr 14, 2024 · Additionally, since organisms often detect CO2 levels indirectly by monitoring the conversion to carbonic acid (a weak acid), we used the exudate assay to evaluate aversion to additional weak acids (formic acid, acetic acid, and propionic acid). WebFor example, hydrochloric acid (HCl) completely dissociates into hydrogen and chloride ions when it is placed in water, so it is considered a strong acid. The acids in tomato juice or vinegar, on the other hand, do not completely …
