摘要: Activity coefficient values for NaCl in ethanol-water mixtures containing 20, 40, 60, 70, 80 and 90 weight % ethanol are calculated from the emf galvanic cell $$Na - glass|NaCl(m), H_2 O (100 Y), EtOH(Y), AgCl|Ag$$ in which of corresponding solvent is indicated parenthesis. The results obtained analyzed by using different theoretical models. Chemical models take into account presence ion pairs solutions high content also used. There good agreement between all
