The answer is Hydrogen Sulfite, because there is only one Hydrogen and its attached to the Sulfite ion.
Hydrogen Sulfite
HSO3 is commonly known as Hydrogen Sulfite.
H2so4 + h2o <==> hso3^-1 + h3o+
HSO3-
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
The chemical equation is:SO2 + H2O ↔ (HSO3)- + H+The acid is hypothetic.
Zinc Hydrogen Sulfate
HSO3 is commonly known as Hydrogen Sulfite.
Cu(HSO3)2
H2so4 + h2o <==> hso3^-1 + h3o+
The chemical formula for zinc bisulfate is Zn(HSO4)2.
The chemical formula of the Marshall's acid is H2S2O8 HSO3-O-O-SO3H.
HSO3-
Ca(HSO3)2 is calcium hydrogen sulfite.
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
The chemical formula for Barium Hydride is BaH2. Ba = Barium H = Hydrogen Its molecular mass is 139.34288 g/mol.
Bisulphite is HSO3, otherwise known as hydrogen sulfite. This has a -1 charge, therefore there is 1 K+ needed to balance this. The chemical formula is thus, KHSO3.
The chemical equation is:SO2 + H2O ↔ (HSO3)- + H+The acid is hypothetic.
