CMC (Critical Micelle Concentration) Study of Some Detergents with or Without Electrolyte and Calculation of Thermodynamic Parameters Using Conductivity Method at Different Temperatures
Year: 2024
Type: article
Abstract: Present study determines the Critical Micelle Concentration (CMC) of some market available detergents at different temperatures in aqueous solutions. For this study we use Sunlight Surf and Safed Surf. Sodium Acetate electrolyte was used. Conductance data was taken at different temperatures (150C, 250C, 350C). From this study it was observed that with increase in temperature, cmc value decreases. Addition of electrolyte with surfactants (detergent), decrease cmc value which support our basic concept of surface chemistry. Different thermodynamic parameters like, ΔG, ΔH, ΔS were calculated and also supporting the formation of cmc.
