Among the organic solvents, the amounts of pK a data in the solvents acetonitrile, DMSO, and DMF from iBonD are among the largest. Due to the large numbers of studies done, many systematic errors related to inconsistent alignment of acidity scales or treatment of solvent effects have also been introduced. For this set of three solvents, we discarded the iBonD data. In their place, we used trusted values from the "Acid dissociation constants in selected dipolar non-hydrogen-bond-donor solvents" project, whose values were critically evaluated and sometimes corrected by us.
