Phosphoric acid is produced in wet process from phosphate rock and
The fugacity of liquid water at 298 K is approximately 3171 Pa. Considering the ideal heat of vaporisation as 43723 J/gm mole, its fugacity at 300 K would be
Sodium tri poly phosphate (STPP) is manufactured by reaction of phosphoric acid with sodium
