Question

Sulphur dioxide + water​

Answer 1

Answer:

it will be an exothermic reaction and beaker can also blast=_==_=

Answer 2

SO2(g) + H2O(l) --> H2SO3(aq)

That's the equation you're expecting. SO2 is much like CO2. They both dissolve in water and they both form fictitious acids. And like the nonexistent H2CO3, there are no molecules of H2SO3, either.

What we call "sulfurous acid" is actually a solution of dissolve sulfur dioxide in equilibrium with some H+ and HSO3- ions.

SO2(aq) + H2O(l) <==> H+ + HSO3-
