Calcium carbonate dissolution in the presence of excess carbon dioxide increased the specific conductance of sea water by approximately 6 x 10-5 ohm-1cm-1 per millimole of carbonate dissolved. The observed conductance increase can be explained by the partial equivalent conductance of calcium bicarbonate and by the hindrance effect of uncharged carbon dioxide dissolved in sea water.
