We investigated the effect of caffeine concentration on the refractive index of aqueous solutions using a high-precision measurement system equipped with a position sensor detector. Experimental results indicated that the caffeine concentration directly affects the deflection distance. This deflection distance serves as the basis for determining the refractive index of the mixture solution. As the caffeine concentration of the mixture solution increases, the refractive index increases. In this study, the caffeine concentration of a mixture was 4%, and the refractive index was 1.3437. Thus, the caffeine concentration of a mixture can be determined on the basis of its refractive index. [ABSTRACT FROM AUTHOR] |
