On the vapor pressure of sulfuric acid
Although nearly 100% sulfuric acid solutions can be made, the subsequent loss of SO3 at the boiling point brings the concentration to 98.3% acid. The 98.3% grade is more stable in storage, and is the usual form of what is described as "concentrated sulfuric acid". Other concentrations are used for different purposes. Some common concentrations are: "Chamber acid" and "tower acid" were the two concentrations of sulfuric acid produced by the le… WebBy this process we were able to reproduce the accepted vapor-pressure curve of pure water throughout the temperature range of -30°C to +15°C, corresponding to vapor …
