| Abstract: | The association constant of the NaSO 4 ? complex has been determined using a sodium-selective electrode in an aqueous medium of 0.5 M ionic strength at 25°C. The constant calculated was 2.5±0.2, and no evidence was found under the present conditions for the existence of higher complexes. |
