| Abstract: |
This table contains selected values for the pK, standard molar enthalpy of reaction {Δ}rH , and standard molar heat-capacity change {Δ}rC p for the ionization reactions of 64 buffers many of which are relevant to biochemistry and to biology. The values pertain to the temperature T = 298.15 K and the pressure p = 0.1 MPa. The standard state is the hypothetical ideal solution of unit molality. These data permit one to calculate values of the pK and of {Δ}rH at temperatures in the vicinity (T=274K to 350K)} of the reference temperature δ= 298.15 K by using the following equations2. |
