Аннотация
An algorithm for calculating the dissociation constants of weak organic acids and bases in water solutions is developed on the basis of spectrophotometric data on the UV and visible regions without measuring the рН of the medium or using buffer solutions. The proposed algorithm is tested experimentally for six single-base acids and single-acid bases of different strengths. The relative error in determining the dissociation constants does not exceed 5% and is in agreement with the literature data.
