Sterilising Action of Acids on Putrifactive Bacteria, Bac. typhosus and Vib. cholerae

First Report. -Sterilising action of Mineral Acids

Abstract

(1) Sterilising action of mineral acids such as HNO₃, HCl, H₃PO₄ is determined by P_H of each solution, and has no relation about kind of acids.
(2) Anions of strong mineral acids have no sterilising action.
(3) There is no special relation between the value of molecular weight of mineral acids and sterilising action.
(4) On sterilising action of cromic acid and HCNO, PH concerns a little.
(5) Sterilising action of dilute cromic acid and HCNO, such as N/100 are almost due to the action of undissociated acid molecule.
(6) The violent sterilising action of Osmic acid is chiefly due to the action of its anion and P_H concerns a little.
(7) Sterilising action of Boric acid is chiefly due to PH and the strilising action of it is very feeble.
