Ocean acidification, driven by CO2 emissions, harms marine ecosystems. Acidification reached 1,000 meters on average by 2014.

Carbon dioxide dissolves in (and reacts with) water, forming carbonic acid. As this acid forms, it breaks down (dissociates) into a hydrogen ion and a bicarbonate ion. The hydrogen ion (produced when ...

However, drinking an acidic beverage like carbonated water does not make your body more acidic. Your kidneys and lungs remove excess carbon dioxide, keeping your blood at a slightly alkaline pH of ...

For decades, evidence like massive outflow channels, ancient river valleys, deltas and lakebeds have suggested Mars had a ...

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 ...

A new theory suggests that liquid carbon dioxide rivers, not water, could have helped shape the surface of Mars.

The carbon dioxide and water react to create carbonic acid ... Sparkling water has a slightly acidic pH. Over time, drinking a lot of it may contribute to the erosion of tooth enamel, says ...

Ocean alkalinity enhancement (OAE) could help absorb more CO2 without harming marine life, based on recent tests.

Medically reviewed by Aviv Joshua, MS Bubbly water is more popular than ever. Staying hydrated is essential to health, but ...
