Rain water contains sulfuric acid and nitric acid. If the concentrations of these acids are high, acid rain occurs.
no
sulphuric acid is a stronger acid than carbonic acid. lower pH defines strength of acid.
Because rainwater is mildly acidic. Acid in the rainwater dissolves the limestone.
No
because it does not contain acid
Sulphuric acid Nitric acid Sulphurous acid Nitrous acid
well you can have acid rain but not all rain is acid rain
corrosion
it is a chemical weathering
Acids in rain water: Sulphuric acid Nitric acid Sulphurous acid Nitrous acid
Carbon dioxide in the atmosphere is dissolved in water, making natural rainwater slightly acidic, so when other gases such as sulphur dioxide are dissolved in rainwater, it becomes more acidic than it would be if it didn't contain carbonic acid.
carbonic acid
