The empirical relation due to Auerbach for evaluating surface tension with the help of ultrasonic velocity and density has been modified by introducing temperature as an additional parameter. The new equation has been shown to be better than the original equation. The modified equation has been applied to obtain precise values of surface tension of five ternary liquid systems [Chlorobanzene (1)+cyclohexane (2)+n-heptane (3), Chlorobenzene (1)+cyclohexane (2)+n-hexadecane (3), Chlorobenzene (1)+cyclohexane (2)+isooctane (3), Chlorobenzene (1)+isooctane (2)+n-heptane (3), 1-chloronaphthalene (1)+isooctane (2)+n-heptane (3)]. These values are then compared with the values obtained by applying different approaches including: Altenberg (AL), Mc-Gowan (McG), Sanchez (SZ), Goldsach and Sarvas (GS) and Flory theory (FT). The results have been presented in terms of their average percentage deviation (APD) values and comparative studies have been done. An attempt has also been made to explain the nature of molecular interactions and force involved in these mixtures.

Abstract


The empirical relation due to Auerbach for evaluating surface tension with the help of ultrasonic velocity and density has been modified by introducing temperature as an additional parameter. The new equation has been shown to be better than the original equation. The modified equation has been applied to obtain precise values of surface tension of five ternary liquid systems [Chlorobanzene (1)+cyclohexane (2)+n-heptane (3), Chlorobenzene (1)+cyclohexane (2)+n-hexadecane (3), Chlorobenzene (1)+cyclohexane (2)+isooctane (3), Chlorobenzene (1)+isooctane (2)+n-heptane (3), 1-chloronaphthalene (1)+isooctane (2)+n-heptane (3)]. These values are then compared with the values obtained by applying different approaches including: Altenberg (AL), Mc-Gowan (McG), Sanchez (SZ), Goldsach and Sarvas (GS) and Flory theory (FT). The results have been presented in terms of their average percentage deviation (APD) values and comparative studies have been done. An attempt has also been made to explain the nature of molecular interactions and force involved in these mixtures.
