This is because the production of oxygen is, so to speak, energetically simpler. However, if a carbonate buffer is added to ...

This process lowers the pH and forms a carbonate buffer system. It takes millennia for carbon sequestered as carbonate to reemerge as CO 2. And because carbonate chemistry is partly governed by pH ...

"As ocean water becomes more acidic, oyster shells begin to dissolve into the water, slowly releasing their calcium carbonate -- an alkaline salt that buffers against acidity. An oyster reef is a ...

The preliminary study has shown that the hydrometallurgical portion of the carbonate plant needs updating. Sayona says a sodium sulphate crystallizer and buffer tanks will need to be added to the ...
