Ca(HSO3)2 is calcium hydrogen sulfite.
Sulfite- SO3-2 (charge of -2)
Al(HSO3)3
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".)
Cu(HSO3)2
HSO3 is commonly known as Hydrogen Sulfite.
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
H2so4 + h2o <==> hso3^-1 + h3o+
Sulfite- SO3-2 (charge of -2)
+1 for H, -2 for each O, +4 for S
