Joseph Lister efficacy of carbolic acid when applied directly to wounds. Therefore, Lister tested the results of spraying instruments, the surgical incisions, and dressings with a solution of carbolic acid. Lister found that the solution swabbed on wounds remarkably reduced the incidence of gangrene. In August 1865, Lister applied a piece of lint dipped in carbolic acid solution onto the wound of a seven-year-old boy at Glasgow Infirmary, who had sustained a compound fracture after a cart wheel had passed over his leg. After four days, he renewed the pad and discovered that no infection had developed, and after a total of
Citric acid ingredients in the production of antiviral tissues. Citric acid is used as an odorless alternative to white vinegar for home dyeing with acid dyes. Sodium citrate is a component of Benedict's reagent, used for identification both qualitatively and quantitatively, of reducing sugars. Citric acid can be used as an alternative to nitric acid in passivation of stainless steel. Citric acid can be used as a lower-odor stop bath as part of the process for developing photographic film. Photographic developers are alkaline, so a mild acid is used to neutralize and stop their action quickly, but commonly used acetic acid leaves
