The Micellar Radii of Dodecanesulfonic Acid as Revealed by Diffusion Experiments at 25`

Abstract

The mean diffusion coefficient at 25°has been determined for dodecanesulfonic acid in perchloric acid solutions. The micellar radii have been estimated. After substantially complete "swamping" the radii gradually increase in size with increase in perchloric acid concentration up to the point where a second phase appears.
