Activity coefficient of hydrochloric acid in the system HCl−KCl−H2O at 25°C and lonic strengths from 0.1 to 3 moles-kg−1

  • J. B. Macaskill
  • Roger G. Bates


The activity coefficient of hydrochloric acid has been determined in HCl−KCl−H2O mixtures at 25°C and for seven values of the ionic strength between 0.1 and 3.0 mole-kg−1, using the cellPt;H2(g, 1atm)\HCl(m A ),KCl B AgCl;Ag

The results are compared with those of previous studies of the same system and are interpreted in terms of ionic interactions specific to the mixture by use of Pitzer's treatment of mixed electrolyte solutions.
