type of reaction
« on: February 18, 2008, 06:04:35 PM »
What type of reactions are involved when an acid is added to a solution containing SO3^2- ion, resulting in the release of gaseous SO2?

Acid base reaction?

??? Do you mean these are different things?

terry33199: sulfurous acid is a weak one.

Decomposition of H2SO3 is not a redox reaction

if one of the products is SO2 where S have oxi. number 4 then it differs from the one in the H2SO4 where is 6. or S is oxidised
