Sodium dodecyl sulfate - Wikipedia

Sodium dodecyl sulfate (SDS) Potassium dodecyl sulfate (PDS) Scheme 2. As can be seen from Scheme 2, a sodium ion replaces the potassium ion. Since the sodium ion has more activity than the potassium ion, i.e.,a Na+ >a K+, the pH values increase gradually and continuously as the concentration of the SDS/KOH system increases.
