The word 'carbonate' is correct and usable in written English.
'Carbonate' is a noun usually used to describe a chemical compound containing an anion of carbonic acid. You can use it when talking about a specific compound or mineral, or when talking about the general presence of carbonates in a certain substance or environment. For example: "The mineral samples contained significant amounts of carbonate."
That change in ocean chemistry would encourage carbon dioxide dissolved in the water to turn into ions of carbonate and bicarbonate, freeing chemical "space" into which carbon dioxide from the atmosphere could flow.The chemically literate will spot a potential snag.
Calcium carbonate deposits dissolve in water that contains carbon dioxide to form calcium bicarbonate, Ca HCO3 2.
And changes in chemistry brought about by the fossil-fuel carbon now accumulating in the ocean will raise the carbonate compensation depth, rather as a warmer atmosphere raises the snowline on mountains.
The one sure way of keeping carbon on the seabed is in the form of calcium carbonate, the main ingredient of most animal shells.
Geological history shows that anthozoans secrete their calcium carbonate skeletons more slowly during periods when there is a lot of carbon dioxide in the atmosphere.
In January, Johansson was appointed the brand ambassador for SodaStream, an Israeli company that produces machines to carbonate beverages.
The molluscs produce proteins which combine with ions of calcium and carbonate in seawater.
They boil the cocoons in a solution of sodium carbonate to separate a protein called fibroin, which is the one they want, from another, called sericin, which they do not.
Many sea-creatures, though, make their shells and skeletons out of calcium carbonate or calcium phosphate materials that dissolve in acids.
Sponges are the oldest living group of multicellular animals, and although most have skeletons made of silica some, like Astrosclera, have a secondary calcium-carbonate skeleton.
The solid-oxide fuel cell requires fancy ceramics for its electrodes and an exotic mixed oxide (yttria and zirconia) as an electrolyte, while the electrolyte in a molten-carbonate cell is so hostile that its electrodes tend to give up the ghost regardless of their composition.Only the remaining two cells, therefore, look like serious candidates for commercialisation.
