They pump hydrogen ions (H +) out of this space to produce more carbonate ions (CO 32-) ions that bond with (Ca 2+) ions to make calcium carbonate (CaCO 3) for their skeletons. Because there are more HCO 3- ions but fewer CO 32- ions in acidified seawater, the corals have to expend more energy to pump out H + ions from …

Tip: To set up a double boiler, place a pot on the stove and pour in at least 2 inches (5.1 cm) of water. Bring the water to a gentle simmer over medium heat and place the bowl with the soaking glue into the pot. The bottom of the bowl shouldn't touch the simmering water. 3. Let the glue solution cool and weigh it.
