Let’s put calcium carbonate on the “dissolving scale” with other stuff. Table salt? That’s a superstar, dissolving in a flash. Sugar? Pretty good too.
Calcium carbonate is more like a couch potato in still water—it just doesn’t want to move. But with a splash of acid, it becomes a hyperactive gymnast, fizzing and disappearing before your eyes.
The Ocean’s Acid Test
This isn’t just a fun lab fact; it’s a huge deal for our planet. Ocean acidification, caused by more CO₂ in the atmosphere, is making seawater more acidic.
That extra acidity makes it harder for creatures like clams, oysters, and corals to build their calcium carbonate shells and skeletons. They essentially start to dissolve before they’re even fully grown. Talk about an identity crisis.
