When carbon dioxide is passed through water, some of it dissolves. A small fraction of the dissolved CO2 interacts with the water to become carbonic acid, H2CO3. Like other acids, this weak acid produces hydrogen ions. These ions react with other substances to produce the characteristic chemical behavior of acids.
The carbon dioxide present in soda water reacts with water to form weak carbonic acid, H2CO3 such as:
H2O(l) + CO2(g) -----------> H2CO3(aq)
H2CO3(aq) + H2O(l) -------> H30+(aq) + HCO3-(aq)
The H3O+ ions formed makes the soda water acidic.

Why Carbon dioxide dissolves in water has got no answer. But it dissolves to form Carbonic Acid which is accepted as its property.

When carbon dioxide dissolves in water it forms carbonic acid. H2CO3
Carbonic acid, H2CO3
pH applies only to aqueous systems. Dissolved in water, carbon dioxide is very mildly acidic.
Carbon dioxide in the atmosphere is dissolved in water, making natural rainwater slightly acidic, so when other gases such as sulphur dioxide are dissolved in rainwater, it becomes more acidic than it would be if it didn't contain carbonic acid.
Carbon dioxide is an acidic oxide. It's a gas that, if it's dissolved in liquids (such as water and also blood) makes that liquid acidic. The more carbon dioxide is dissolved in the liquid the more acidic it gets. So if you don't exhale carbon dioxide but still inhale it the blood turns acidic. This is what happens when you hyperventilate. More carbon dioxide is absorbed during inhalation than is emitted during exhalation. This is a simplified explanation so please don't quote me in academic circles.
Soda is carbonated, meaning that it has carbon dioxide dissolved in it. Some of this carbon dioxide (CO2) reacts with water (H2O) to form carbonic acid (H2CO3), which makes it acidic
- the carbonic acid (dissolved carbon dioxide in water) is not toxic - the carbonic acid (dissolved carbon dioxide in water) is not so corrosive - the carbonic acid (dissolved carbon dioxide in water) has a pleasant taste - the carbonic acid (dissolved carbon dioxide in water) is cheaper - the carbonic acid (dissolved carbon dioxide in water) is very simple to prepare and very accessible
Water with dissolved carbon dioxide is acidic.

Co2 is a acidic gas. water turn acidic when CO2 dissolved.
Rainwater is normally acidic because the carbon dioxide in the air which mixes with rainwater to form weak acid. That's why its acidic ^_^ Rainwater is also because of the pollutions in the air and it mixes with the water so its not good. meee!

pure water is slightly acidic because of dissolved carbon dioxide

No. It simply dissolves. If added to an acidic solution such as vinegar it will release carbon dioxide.

Yes. The dissolved carbon dioxide (carbonation) makes soda water a very weak solution of carbonic acid.
Atmosphere has the higher concentration of carbon dioxide. If water had a high concentration of carbon dioxide then water would be acidic because it would result the formation of carbonic acid, but water is neutral. The fact that dissolved carbon dioxide create carbonic acid is used in the manufacture of Coca-Cola. So I think it is the atmosphere.
