Condensation of water from the air upon hygroscopic crystals

Abstract

This paper describes experiments on the conditions of deliquescence of the crystalline salts found in dust records from the air, and has a bearing on the formation of haze, fog, and condensation from the air. The possibility of identifying the nature of such salts when in very minute particles, so small that micro-chemical and crystallographic methods cannot be used, is indicated, the method being based upon the vapour pressure of deliquescence.
