| http://www.w3.org/ns/prov#value | - SO2, when added to an acidic medium like wine, disassociates a proton (H+) so that most of the ???sulfite??? is in an ionic form and should be referred to as the ???bisulfite ion.??? This is what winemakers refer to as ???free SO2??? because it is ???free??? to react with compounds, such as aldehyde or oxygen.
