摘要：

Dissociation constants of lactic acid (2-hydroxy propionic acid) have been studied at different temperatures between 25 to 50degreesC interval in aqueous media and in mixed organic-water solvent systems (dioxane-water, ethanol-water and methanol-water) at 25degreesC. Potentiometric data was analysed for calculation of pKa values of monobasic acids. Results shows that pKa values are higher in mixed solvents as compare to in aqueous media. Significant effect of temperature and solvent's nature on pKa values has been observed.
