The equilibrium is pH dependent with the predominate form at wine pH being bisulfite. Most of the rest is molecular and very little, if any, remains in sulfite form. These forms make up what is termed as ‘free SO2’.

WebbAnd then if we are anywhere above 9.69 than the form that is going to predominate is going to be the fully deep rotated form. So a P H equals one.
