Title: How to keep HCl vapour concentration constant in HCl-H2O system at say 60°C
Post by: IITian on August 27, 2008, 02:20:58 PM

I have a simple question  ???

How to keep the vapour concentration of HCl above a HCl-H2O mixture constant when the solution is at 60°C. I know you can get an azeotropic mixture with ~20.2% HCl in water which boils at ~108°C, but I am not interested in boiling the mixture. I am keen on getting a constant HCl vapour composition at 60°C. The maximum I can go is 80°C, but I would rather not!

Your help is anticipated & appreciated ;)
