摘要：

The apparent dissociation constants of carbonic acid (K1K* K2*) were determined at atmospheric pressure by potentiometric titrations in artificial seawater. Constants (K1* and K2*) were extracted from the experimental titration curves both by a non-linear curve-fitting procedure, and by using the Gran functions. There is good agreemente between the two mathematical calculations for both constants. Throughout the salinity range of 10 < S < 50 and the temperature range of -1°C < Ti < 40°C this new data set agrees closely with the previous set of I HANSSON His results, combined with the present ones and fitted as a function of temperature and salinity, satisfy two relationships which are given in the paper.
