Abstract
10-hydroxydecahydryacridinedione derivative was synthesized by the reaction of dimedone, hydroxylamine and salicylaldehyde in dry pyridine. This substance is colorless in acidic and neutral and pink in base solutions. The acid dissociation constant of this compound in a hydroalcoholic solution was determined by the UV-visible spectroscopic technique. It was shown that the obtained compound can be used as an indicator for the titration of strong acids and bases. Titration standard 0.1 n solution of sodium hydroxide with standard 0.1 n solution of hydrochloric acid using of this compound as indicator has been successful

Keywords
10-hydroxydecahydryacridinedione derivative, acid dissociation constant, indicator for the base-acid titration
