Abstract
The stoichiometric dissociation constant, pK*, of TRISH+ has been determined from emf measurements in NaClO4 solutions to 6.0m at 25°C. The results have been used to derive Pitzer coefficients for the interaction of TRISH+ with ClO −4 . The coefficients have been compared to the values in NaCl solutions. The values of pK* for TRISH+ can be used to calibrate pH electrodes in NaClO4 solutions using TRIS buffers.
