I believe the pH of H2SO3 (or sulfurous acid) is 1.5.
H2SO3 is an acid. It is a weak acid known as sulfurous acid.
The formula for sulfurous acid is H2SO3.
The hybridization of the sulfur atom in H2SO3 is sp2.
The pH of sulfur dioxide itself is not relevant since it is a gas and does not dissociate in water to produce ions. However, when sulfur dioxide dissolves in water, it forms sulfurous acid (H2SO3), which can lower the pH of the solution due to the release of H+ ions.
Dihydrogen Sulfur Trioxide or sulfurous acid
H2SO3 will ionize to H+ + HSO3-. The Keq = [H+][HSO3-]/[H2SO3]HSO3- will ionize to H+ + SO3^2-. The Keq = [H+][SO^2-]/[HSO3-] ... very small value
When sulfur dioxide is dissolved in water, it forms sulfurous acid (H2SO3). This reaction can lead to the acidification of the water, lowering its pH. Sulfurous acid is a weak acid that can further react to form sulfite ions (SO3^2-) and bisulfite ions (HSO3^-).
The correct name for the compound H2SO3 is sulfurous acid.
correct name of H2SO3 is hydrogen sulphite .And for H2SO4 it is hydrogen Sulphate.
H2S2O8 has a larger percent by mass of sulfur because it contains two sulfur atoms in each molecule compared to one sulfur atom in H2SO3.
Sulphuric acid = H2SO4
H2so3
