Abstract

V magistrskem delu sem določala srednji aktivnostni koeficient NaBr v vodni raztopini in v raztopini polielektrolita. Polielektrolit je ionen (4,5- in 6,12-ionen bromid). Srednje aktivnostne koeficiente sem določala eksperimentalno, z merjenjem elektrodnega potenciala, ter teoretično, s pomočjo Ornstein-Zernikove integralske enačbe v HNC (ang. hypernatted chain) približku. Teorija dobro opiše srednje aktivnostne koeficiente NaBr v vodni raztopini, slabo pa opiše srednje aktivnostne koeficiente NaBr v raztopinah polielektrolitov.

Secondary title: The influence of the polyelectrolyte on the mean activity coefficients of NaBr in aqueous solutions
Secondary abstract: In this master thesis, mean activity coefficients of NaBr in aqueous solution and in solution of polyelectrolytes was determined. 4,5-ionene bromide and 6,12-ionene bromide were used as polyelectrolytes. Mean activity coefficients were determined experimentally, by measuring voltage of a galvanic cell, and theoretically, using Ornstein-Zernike integral equation with HNC (hypernatted chain) closure. Theory describes mean activity coefficients of NaBr in aqueous solutions well, but poorly describes mean activity coefficients of NaBr in solutions of polyelectrolytes.
