When carbon dioxide dissolves in water, it can do so as a gas dissolved in water or by reacting with water to produce carbonic acid. Carbonic acid is known as a weak acid because it partially dissociates into the positive Hydrogen ions and negative bicarbonate ions.his means that some of the added hydrogen ions will react with the bicarbonate ions to produce carbonic acid and the carbonic acid will dissociate into carbon dioxide and water as shown below. When hydrogen ions are removed from the reaction, the equilibrium will shift to the right.
Carbonic acid is formed when carbon dioxide is dissolved in water and can only exist in a solution. It is a weak, unstable dibasic acid and that forms carbonate and bicarbonate salts.Carbonic acid can gives two series of salts: carbonate and hydrogen carbonate salt.Carbonic acid dissolves rocks, metals, minerals, and it can form caves.t is made from mostly carbon dioxide and it is not a very strong acid. You can find it in soda pop and many other things. It is corrosive on limestone and calcium, which causes many caves to form over a period of time as it eats away at the rock.
