YES
No, sulphuric acid is stronger than sulphurous acid. Sulphuric acid is a strong acid that can fully dissociate in water to release hydrogen ions, while sulphurous acid is a weak acid that only partially dissociates.
The chemical formula for sulphurous acid is H2SO3.
Sulphurous acid is not a reaction (chemical or physical); the sulphurous acid (H2SO3) is a chemical compound.
Sulphuric acid = H2SO4
Sulphur dioxide (SO2) reacts with oxygen in the air to form sulphurous acid (H2SO3). This reaction occurs when SO2 dissolves in water, creating a weak acid known as sulphurous acid. Sulphurous acid is commonly found in the atmosphere as a result of industrial processes and volcanic emissions.
in sulphurous acid sulphur atom is surrounded by three oxygen atoms and has a lone pair of electrons so the electrons pairs of O-H bonds are not attracted towards sulphur and hydrogen can not be removed as H+ ion,the lone pair of sulphur is also responsible to attract the separated H+ ion,therefore the removal of H+ ion from sulphurous acid is not easy and it is a weak acid, in sulphuric acid sulphur is surrounded by four oxygen atoms and has no lone pair of electrons.

Its name is "sulphurous acid". So it is quite obviously an acid, not a base!
Acids in rain water: Sulphuric acid Nitric acid Sulphurous acid Nitrous acid
Sulphurous acid is formed when sulphur dioxide dissolves in water. Sulphuric acid is formed when sulphur trioxide dissolves in water. Over time, sulphurous acid will oxidize to sulphuric. SO2 + H20 -> H2SO3 (sulphurous acid) SO3 + H20 -> H2SO4 (sulphuric acid)
Sulphur dioxide reacts with water to form sulphurous acid. The word equation for this reaction is: sulphur dioxide + water --> sulphurous acid.
