Chapter 10, Problem 10-56(choose chapter or problem)
Constant-boiling aqueous HCl can be used as a primary standard for acid-base titrations. When ~20 wt% HCl (FM 36.461) is distilled, the composition of the distillate varies in a regular manner with the barometric pressure: P (Torr) HCla (g/100 g solution) 770 20.196 760 20.220 750 20.244 740 20.268 730 20.292
