Question

What happens when to co2 when added to water?

Answer 1

Carbon dioxide is an dehydrated acid. When carbon dioxide is added to water it forms carbonic acid according to the equation:

CO2(aq) + H2O(l)  --> H2CO3(aq)

Carbonic acid is a weak acid so some of it ionizes to produce Hydrogen ions (hydronium ions in the presence of water)

H2CO3(aq) + H2O(l) --> HCO3-(aq) + H3O+(aq)

This is why water exposed to the atmosphere is has a pH of around 5, slightly acidic.

Answer 2

CO2...that's carbon Dioxide, right?  it's like dry-ice and water...when combined, it creates fog (like those fog machines).  Great effect for lazer tag!

Answer 3

the water molecules become hydronium molecules (H3O)
