The equilibrium constant for the reaction of tri-n-butyl phosphate with associated nitric acid was calculated to be 19.9 plus or minus 0.5. The equilibrium distribution constant for the partition of associated nitric acid into tri-n-butyl phosphate was determined as 0.19. The equilibrium constants obtained were used to calculate the concentration of associated nitric acid in dilute aqueous nitric acid solutions. These calculations were made from the equilibrium distribution curve for nitric acid between tri-n-butyl phosphate and water at 25° over the concentration range of 6 to 12M aqueous nitric acid.
