Acidic Rain
Affects of acidic rain
Crops do not grow well in acidic soil
Acidic lake prevents fish eggs to hatch and kills fish and insects
Increases weathering of limestone
Corrodes metal e.g iron and weakens them
Harms forests
Wind spreads solution
Can occur in snow
Caused by humans
Car Engines
Internal combustion
Fuel + air mixed together
Nitrogen and air temperatures can make nitrous oxides
Nitrous oxide causes acidic rain
Nitrogen oxide can cause toxic red brown gas which causes bronchitis
Sulfur
Hydrocarbons can contain naturally occurring sulfur compounds
These impurities can be removed in oil refineries
Sulfur + oxygen = Sulfur dioxide which causes rain
pH
pH of rain is 5 - 5.5
Acidic rain is a pH of less then 4
Catalyst converter
Convert ntrous oxides in exhaust gasses to harmless nitrogen
