Proton-controlled mechanism for coupling among proton production/consumption reactions in CaCO3-oversaturated waters or calcifying organism-inhabited seawaters
Abstract:KEYWORDSThe CaCO3-oversaturated weakly basic water at around pH=8 was proved by the novel simple equations (e.g. log [Ca 2+ ] = -2pH -logPCO2 + 9.94) derived from material energetics and protoncontrolled mechanism for coupling among proton/hydroxide production/consumption reactions (e.g. CaCO3 + H + ↔ HCO3 -+ Ca 2+ ) in equilibrium with atmospheric carbon dioxide. The cyclic/oscillating variation between pH=8.3 and 8.0 for marine calcifying organisminhabited paleo and preindustrial seawaters was elucidated by … Show more
