The oceans are the Earth's largest carbon reservoirs. What property of water allows the oceans' water to store carbon dioxide ?

Carbonic acid releases hydrogen ions, which combine with carbonate in seawater to form bicarbonate, a form of carbon that doesn't escape the ocean easily. As we burn fossil fuels and atmospheric carbon dioxide levels go up, the ocean absorbs more carbon dioxide to stay in balance.Carbon dioxide is naturally stored in the ocean through chemical processes, either as a dissolved gas or, over a longer time scale, as carbonate sediments on the seafloor. In fact, more than 70 percent of current CO2 emissions will eventually wind-up in the ocean.

idk what the options are but

these is a strong electrostatic attraction between the ions hence a lot of energy is needed to overcome this attraction

this is why the boiling points are so high

d. groundwater flows through the subsoil and deposits minerals.
