The heat of hydration of dry sulfonic acid resin in different concentrations of sulfuric acid has been determined. The heat of hydration of the resin in H2O is 143. 4 J/g(resin). The greater the concentration of sulfuric acid, the less the heat will be released. The hydrate formed from three sulfonic acid groups and one water molecule is the most stable one of all the hydrates of sulfonic acid resin and water.
