Acid rain is caused by emissions of compounds of ammonium, carbon, nitrogen, and sulfur which react with the water molecules in the atmosphere to produce acids. You get acid rain mainly through industrial emissions. Hope that answers your question 😉
Acid rain is when gases certain react with water droplets in the atmosphere to form an acidic solution (i.e. pH lower than pure water, pH7). These gases are normally caused by burning of fossil fuels, so for example by power stations, vehicles burning petrol or gasoline, houses burning wood or coal, etc.
The common gases (greenhouse gases) emitted from burning of fossil fuels include CO2 (carbon dioxide), SO2 (sulphur dioxide) and NOx (nitrogen oxides). These can all react with water (H20) in the atmosphere to form acidic solutions. Many parts of Scandinavia, such as Sweden and Norway, have been hugely affected by Britain’s burning of fossil fuels in the past….our powers stations in particular were responsible for producing large quantities of sulphur dioxide and NOx gases which drift over to Scandinavia produce acid rain and have caused damage to wildlife amongst other things.
In more recent years, international legislation has meant reductions in emmisions of SO2 and NOx, which has gone someway towards reducing acid rain, but it still exists.
Acid rain is caused by chemicals like ammonium, carbon ,nitrogen and sulfur from emissions (cars, trains, planes, homes, factories, etc.) being released into the atmosphere and interacting with water molecules forming acid rain.
