Two novel approaches in ion‐pair formation‐based potentiometric titrations of anionic surfactants are presented. First, a new type of the low ohmic coated‐wire ion‐selective electrode is introduced; the polymeric membrane containing a plasticizer mixed with carbon powder. Second, didecyldimethylammonium chloride as the cationic titrant is for the first time proposed and applied, providing the titration curves with the highest potential jump.
