Activity Coefficients of HCl in Solutions Related to "Tris" Buffers in Artificial Seawater. II. HCl + NaCl + TrisHCl + H2O, and Tris Buffer + NaCl + H2O, to High Ionic Strength and from 5 to 40 °C

{{output}}
The substance Tris (2-amino-2-hydroxymethyl-1,3-propanediol, CAS 77-86-1), and its protonated form TrisH+, are used in the preparation of 'total' pH buffers in artificial seawater media. The development of a chemical speciation model of the buffer solutions,... ...
