Sulphuric acid = H2SO4
It's H2SO3
H2SO3 is the chemical formula for sulphurous acid.
Sulphuric Acid is H2SO4 Sulphurous Acid is H2SO3 Oleum(fuming sulphuric acid) is H2S2O7 ( Also known as pyrosulphuric acid ; very nasty stuff).
Sulphuric acid is H2SO4 It is a combination of two hydrogens , one sulphur and four oxygens. NB Do NOT confuse with 'sulphurous acid' , which is 'H2SO3'. Nor Oleum (fuming sulphuric acid), which is H2S2O7 (Very nasty stuff).
It is just another name for Sulphurous acid = H2SO3

Assuming you're asking for the chemical symbol - it is... C6H8O6
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.
YES
The chemical symbol for sulphuric acid is H2SO4.
There is NO symbol for nitrous acid. However it has the formula ' HNO2'. Compare with nitric acid Nitrous Acid = HNO2 Nitric Acid = HNO3 NB Note the number of oxygen present.
