MARQUES, A.; FERRA, M.I.A. BANDEIRA, M.H.. Activity coefficients of potassium chloride in aqueous solutions of potassium chloride and potassium phthalate. []. , 24, 2, pp.295-303. ISSN 0872-1904.
Mean activity coefficients of potassium chloride were determined in aqueous solutions of potassium chloride and potassium phthalate, in the temperature range 10-50 ºC and ionic strength range 0.05-4 mol kg-1, from potentiometric measurements on a galvanic cell without liquid junction. By processing the results using the Pitzer model, interaction parameters for potassium phthalate were calculated as well as their temperature dependence.
