What Is the Ostwald Process? - wiseGEEK

The Ostwald process produces nitric acid as an aqueous solution of about 60% concentration. By distillation, the concentration is increased to 68.5%, giving the reagent-grade nitric acid that is used for most purposes. This acid is an azeotrope of nitric acid and water, meaning that the two compounds boil at the same temperature — 251.6 °F ...
