| Comment: |
raw data from [Y75], [W73], [WH75]; 0.1-0.001M KNO3; pK from figure 16 and 18 (other in table 8!); PZC=PZNPC calculated in [LMB95] (PZC=1/2(pK1+pK2) for infinite dilution; SSA from original reference; SSD from [Y75] (tritium exchange and geometrical calculation; there 12.2 for geometrical calcualtion and 12.5 for tritium exchange) |
