The control of acidity in the physiological pH range 6 to 8 is of importance in the biomedical field. The buffer compound TAPSO has been studied. Conventional paH values for four physiological buffer solutions have been studied: (i) 0.05 molal TAPSO + 0.05 molal sodium TAPSOate; (ii) 0.05 molal TAPSO + 0.05 molal NaTAPSOate + 0.11 molal NaCl; (iii) 0.08 molal TAPSO + 0.08 molal NaTAPSOate; and (iv) 0.08 molal TAPSO + 0.08 molal NaTAPSOate + 0.08 molal NaCl; at temperatures 25 and 37°C and have been assigned based on Pitzer's theory and Bates-Guggenheim convention. The results are useful in clinical studies.
