title: Thermodynamic dissociation constant studies of caffeine at different temperatures and in organic water solvent mixture.
abstract: Thermodynamic dissociation studies have been carried out potentiometrically at various temperatures from 25 to 50 degrees C and in 10, 20, 30 and 40% v/v dioxane-water solvent mixture at 25 degrees C. The influence of temperature and nature of solvent on dissociation equilibria of caffeine is being investigated. A computer program in GW-BASIC has been used to calculate the pK values.
