On the Nature of Foam. II. The Foam Formation of Ternary System, Acetic Acid–Ethyl Ether–Water

(1) The foam formation of the liquid ternary system of acetic acid–ethyl ether–Water was measured by means of a shaking apparatus which was properly constructed for this purpose. (2) The life time of foam produced and the height of foam zone have been measured. (3) The diagrams were made between the degree of foam formation and the composition, and several conclusions were obtained on the foam formation of the mixture belonging to homogeneous and heterogeneous regions of the above ternary system.
