Abstract
The partial molar volume of dodecyltrimethylammonium hydroxide in wate r and aqueous NaOH solutions was measured. The addition of NaOH did no t affect either the micellized or the unmicellized molecules. The expa nsion on micellization is much larger than in dodecyltrimethylammonium bromide systems, which reflects the stronger ionization of the hydrox ide surfactant micelles, when compared with that of the bromide amphip hile.
