Özet:

 

pH changes as a function of concentration for sodium dodecyl  sulfate (SDS) and dodecyltrimethylammonium bromide (DTAB) were  observed by the addition of 1 N HCl and 1 N KOH. pH values increased  up to the critical micellar concentration (CMC) for the SDS/HCl system  and decreased for the DTAB/KOH system.  In the SDS/HCl and DTAB/KOH  systems, the micellar phase had a fixed composition and was  homogeneous and monodisperse above the CMC. However, in the SDS/KOH  and DTAB/HCl systems, pH values increased in a continuous and gradual  manner below and above the CMC, and the properties of the micellar  phase changed with temperature as a function of concentration, giving  rise to inhomogeneity and polydispersity.
