Abstract
Density, viscosity and excess parameters of nicotinium dichromate in protic and aprotic solvent media
Author(s): Monalisa das, Sunil Kumar Pradhan, Smrutiprava Das and Ajaya kumar PatnaikThe densities and viscosities of nicotinium dichromate with DMSO and methanol have been measured at 303.15K. The values are used to calculate the apparent molar volume ( ) Vf , limiting molar volume ( ) 0 Vf , excess molar volume ( E ) m V , viscosity deviation (Dh ) and excess Gibb’s free energy of viscous flow ( ) E DG* . The viscosity results have been computed to calculate Falkenhagen coefficient (A) and Jones-Dole B coefficient. The main aim of the study is to correlate the excess properties with molecular interactions present in the solution. The strength if interaction is related to the nature of solvents.
