| Coca-Cola has a pH of 2.5, which is slightly more than lemon juice and slightly less than orange juice. Don't worry, it's not dangerous because our stomach has an acidic environment.

| ==== Headline ==== | ==== Acid Rain ==== |
| Acid rain is mainly caused by atmospheric pollution from sulfur dioxide, which forms sulfuric acid when dissolved in water. Sulfur dioxide is emitted during the burning of fossil fuels. In recent years, the percentage of nitric acid in acid rain has been increasing as a result of reducing sulfur dioxide emissions - but sulfuric acid is still the main culprit.

| ==== Pure water pH ==== | ==== Pure water pH ==== |
| Pure water has a pH near 7 at room temperature, but this value decreases with increasing temperature. It is also worth noting that water exposed to air becomes slightly acidic due to the absorption of carbon dioxide.
