Question

Как из MgSO3 получить H2SO3 ?

Answer 1

MgSO3 + 2HCl = H2SO3 (неустойчива, распадается на H2O и SO2↑) + MgCl2

Answer 2

MgSO3 + 2HCl = MgCl2+ H2SO3
                                       /      \ 
                                   H2O   SO2

Answer 3

Obtaining H2SO3 from MgSO3

To obtain H2SO3 from MgSO3, you can follow the following chemical reaction:

MgSO3 + 2HCl → MgCl2 + H2SO3

This reaction involves reacting magnesium sulfite (MgSO3) with hydrochloric acid (HCl) to produce magnesium chloride (MgCl2) and sulfurous acid (H2SO3).

This process involves the reaction of an acid with a metal sulfite to produce the desired sulfurous acid.

I hope this helps! If you have any other questions, feel free to ask.
