Investigation of chemical sound absorption in sea water. Part IV
The low-frequency boric acid relaxation mechanism in seawater has been identified as an acid-base exchange between the B(OH)3/B(OH)−4 and HCO−3/CO2−3 equilibria. Ion pairing with Ca2+ is also involved and a coupled-system model is proposed. Supporting experimental data for the CO2 exchange mechanism...

| Zusammenfassung: | The low-frequency boric acid relaxation mechanism in seawater has been identified as an acid-base exchange between the B(OH)3/B(OH)−4 and HCO−3/CO2−3 equilibria. Ion pairing with Ca2+ is also involved and a coupled-system model is proposed. Supporting experimental data for the CO2 exchange mechanism are presented. Similar exchanges with ammonia and silicic acid are also investigated. |
