What is acid rain?
Some pollutant gases can be present enough to undergo reactions with water and become dilute acidic drops.eg SO3 +H2O ---> H2SO4 (sulphuric acid)eg N2O5 + H2O ----> 2HNO3 (nitric acid)eg CO2 + H20 ---->H2CO3 (carbonic acid)Over time they can "pit" statues and rocks, put little holes in vegetation and change the pH slightly of ponds.You don't have to run for your life,would you run from other acids like acetic acid (vinegar), lactic acid (milk) or citric acid (oranges and lemons)
A rain in highly polluted areas that can burn to the touch, they both appear in real life and fiction like in Star Wars. Hope this helped!
Its burns through everything..Look it up in a science book.
contaminants that are present in the air..when it rains...
