Data from ultrasonic absorption in synthetic and natural seawater can be used to calculate pairing of magnesium and sulfate ions in seawater. Calculation under the assumption that data from ion pairing in single salt solution can be applied to seawater solution results in a value of 9.2 percent for the amount of magnesium paired with sulfate and 17.5 percent for sulfate paired with magnesium.
