Carbon dioxide reacts with water to produce carbonic acid. The double arrow means that carbonic acid breaks down pretty readily to form carbon dioxide and water again. A hydrogen atom from the ...

During chemical weathering, rocks could then suck up CO2 when some minerals were attacked by the weak acid in rainwater. This ...

The ocean naturally pulls in about a quarter of the carbon dioxide people produce. It's the planet’s largest carbon sink.

When the carbon dioxide mixes with the water in the red cabbage indicator, it creates a very weak acid called carbonic acid. This acid reacts with the red cabbage indicator and changes its color. The ...

Carbonic acid is relatively weak ... as they absorb more and more of the carbon dioxide that's coming from tailpipes and smokestacks. Hall-Spencer has been studying the sea around the island ...

Carbonic acid causes the acidity in fizzy drinks. This is used as a test for carbon dioxide. When carbon dioxide is bubbled through limewater the limewater changes from colourless to milky.

and two liquids—an acid and a base. The reaction traps carbon already in the water by forming a solid similar to seashells. The process also makes an alkaline slurry that can absorb CO2 directly ...
