what is organic acid
An organic acid is an organic compound with acidic properties. The most common organic acids are the carboxylic acids, whose acidity is associated with their carboxyl group âCOOH. Sulfonic acids, containing the group âSO 2 OH, are relatively stronger acids.Alcohols, with âOH, can act as acids but they are usually very weak.he conjugate bases of organic acids such as citrate and lactate are often used in biologically-compatible buffer solutions. Citric and oxalic acids are used as rust removal. As acids, they can dissolve the iron oxides, but without damaging the base metal as do stronger mineral acids.
