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 ClO₄^–. 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.

Keywords:	Acid dissociation constants emf TRISH TRIS buffers Pitzer coefficients
