Acid rain

Usually rain is naturally acidic-5.6 this is due to carbon dioxide, occurring naturally in the atmosphere, dissolves into the rain forming carbonic acid

the name given to precipitation over PH 5.6 due to a combination of pollution problems caused by a range of acidic gases and other pollutants which contribute

• sulphur dioxide • sulphur trioxide • oxides of nitrogen

1) sulphur dioxide emitted through the burning of fossil fuels reacts with water to produce a weak acid of sulphurous acid

1) when sulphur dioxide is converted to sulphur trioxide due to he presence or other pollutants (tropospheric ozone / nitrogen dioxide) 2) sulphur trioxide dissolves into rain water forming a strong acid- sulphuric acid

1) nitrogen dioxide dissolves into rain forming a strong acid- nitric acid

1) dry acid deposition 2) wet acid depostion

1) dry acid deposition 2) wet acid depostion

1) dry= sulphur di/trioxides affect the environment themselves 2) wet= when SOx gases dissolve into rain water and the acid rain affects the environment

1 )crossion of metals ie railway lines, over head powerlines ect 2) limestone structures such as buildings and statues become damaged 3) harm living organisms

1) Tissue damage 2) breathing difficulty

1) solubility of nutrients may be affected 2) formation of toxic ions- inhibit enzyme activity 3) leaching of toxic ions harming aquatic organisms
