Acid rain is rain that is more acidic than in its natural state, and is usually consider to be a pH of less than 5. (Natural rain water is slightly acidic due to the presence of dissolved [[carbon dioxide]]. Acid rain forms when [[sulphur dioxide]] dissolves in [[water]] to make [[sulphurous acid]]. The [[sulphur dioxide]] can also be oxidized to [[sulphur trioxide]] and form [[sulfuric acid]] upon reaction with [[water]]

Acid rain can cause damage to structures and statues, and also plant life. (For example the [[Black forest]] of [[Germany]] has been heavily damaged by acid rain.) The combined action of carbonic, sulphuric and nitric acid can dissolve limestone statues on account of a neutralisation reaction.
