THE report of a discussion on this subject1 prompts me to publish a simple equation which I obtained some time ago for the water vapour pressure isotherm of sulphuric acid solutions. Sulphuric acid is the only liquid that gives heats of mixing with water which are comparable with the heat of wetting of wool, and because the solution is free from mechanical restraint, I set out to determine how far the solution deviated from the regular solution formula2.
