Bisulfite
The formula of the ion hydrogen sulfite with a charge of -1 is HSO3-.
The valence of a bisulphite ion is -1; its formula is HSO3-1. (Although the name bisulphite is still acceptable, it is now considered preferable to call it "hydrogen sulfite ion".)
Ca(HSO3)2 is calcium hydrogen sulfite.
The chemical formula for copper(II) hydrogen sulfite is Cu(HSO3)2.
The chemical name for Zn(HSO3)2 is zinc hydrogen sulfite.
The formula of the ion hydrogen sulfite with a charge of -1 is HSO3-.
HSO3 is commonly known as Hydrogen Sulfite.
The conjugate base of HSO3- is SO32-. This is formed when HSO3- donates a proton.
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 formula for zinc bisulfite is Zn(HSO3)2.
When HSO3- is added to water, it will dissociate into bisulfite ions (HSO3-) and hydrogen ions (H+). The bisulfite ions will react with water to form sulfurous acid (H2SO3).
The valence of a bisulphite ion is -1; its formula is HSO3-1. (Although the name bisulphite is still acceptable, it is now considered preferable to call it "hydrogen sulfite ion".)
HSO3- is a stronger base than SO32- because it can accept a proton (H+) more readily. The presence of the H+ ion in HSO3- makes it more capable of accepting another proton compared to SO32-.
Ca(HSO3)2 is calcium hydrogen sulfite.
SO32
The formula for magnesium hydrogen sulfite is: Mg(HSO3)2
The chemical formula for copper(II) hydrogen sulfite is Cu(HSO3)2.
