SUMMARY
The carbon dioxide solubility coefficient, a^, and the apparent carbonic acid dissociation constants, K [ and K{,, were estimated in the serum of the crab Carcinus maenas at various temperatures and ionic strengths. At 15 °C, the indirectly determined aOOt value is 0-0499 m-mole I " 1 torr"...
