Abstract

Bu çalışmada, dissosiasyon ortamında benzoik asit çözeltilerinin sıcaklık ve konsantrasyon ile dissosiasyon özelliklerinin değişimi UV-VIS Spektrofotometrik yöntem ile incelenmiştir. Her çözelti sistemi için, farklı sıcaklıklarda konsantrasyon, c, ve absorbans, A, arasındaki ilişkiler belirlenmiştir. Elde edilen sonuçlar, benzen, etil alkol, n-propil alkol, iso-propil alkol and N,N-dimetilformamid çözücüleriyle hazırlanan çözeltiler için Lambert-Beer yasasının sırasıyla 1.00x10-3M to 6.25x10-5M; 1.00x10-4M to 6.25x10-6M; 1.25x103M to 7.80x10-5M; 2.00x10-4M to 1.25x10-5M; 1.00x10-3M to 6.25x10-5M derişim aralıklarında geçerli olduğunu göstermiştir. Çözeltilerin molar sönüm katsayıları Lambert-Beer kanunu yardımıyla hesaplanmıştır. Her çözelti sistemi için molar sönüm katsayısının sıcaklık bağımlılığı belirlenmiştir

Abstract

In this study, the dissociation properties of benzoic acid that change with temperature and concentration in the dissociation media were investigated by UV-VIS spectrophotometry. For every solution systems, the relationships between absorbance, A, and concentration, c, were obtained at different temperatures. The results were indicated that the Lambert-Beer law was obeyed in the concentration range of 1.00x10-3M to 6.25x10-5M; 1.00x10-4M to 6.25x10-6M; 1.25x10-3M to 7.80x10-5M; 2.00x10-4M to 1.25x10-5M; 1.00x10-3M to 6.25x10-5M for the solutions which are prepared with benzene, ethyl alcohol, n-propyl alcohol, iso-propyl alcohol and N,Ndimethylformamide; respectively. Molar absorptivities of the solutions were calculated by using the LambertBeer law. The temperature dependence of the molar absorptivity of each solution was determined
