  • Acid Rain
    • Rainwater always has some carbon dioxide in it, which makes it slightly acidic.
    • Other gases produced in power stations and car engines can also dissolve in water in the air – these gases include sulphur dioxide. 
      • They make the rain more acidic – rain that is more acidic than normal (less than about pH 5.2) is called acid rain.
    • Acid rain makes lakes and rivers acidic, which harms fish and other life. It also damages trees, buildings made of limestone or marble, and makes metal corrode. 
    • The amount of acid rain falling in Europe and North America has been reduced by removing sulphur from car fuels and by removing sulphur dioxide from power station waste gases.
