The solubility of aragonite in seawater—I. Effect of pH and water chemistry at one atmosphere

The effect of water chemistry on the solubility of aragonite in seawater has been defined experimentally as a series of apparent solubility products measured with respect to pH at one atmosphere.The dominant control of the apparent solubility product of aragonite is the carbonate ion concentration, and this is primarily a function of pH. In the light of this fact, we have reconciled our data with 81 other reported values of aragonite solubility by simply examining the water chemistry of the waters in which they were determined.
