Abstract(s)

Mean activity coefficients of NaCl have been calculated, by means of the Pitzer theory,in mixed solutions of NaCl and NaH2PO4 and of NaCl and Na2HPO4, with ionic strength lower than 2 mol kg-1, at 25 ºC. Electromotive force measurements, using a silver, silver chloride and a sodium ion selective electrodes, show nernstian response, in those mixed electrolyte solutions.
