MEASUREMENT OF THE APPARENT DISSOCIATION CONSTANTS OF CARBONIC ACID IN SEAWATER AT ATMOSPHERIC PRESSURE1
Abstract
The apparent dissociation constants of carbonic acid in seawater were determined as functions of temperature (2–35°C) and salinity (19–43 ‰ ) at atmospheric pressure by measurement of K’x and the product K'� K'2. At 35%° salinity and 25°C the measured values were p K ′ 1 = 6.000 and p K ′ 2 = 9.115; at 35 ‰ and 2°C the measured values were p K ′ 1 = 6.177 and p K ′ 2 = 9.431.
