Voorbeeld

In de volgende tabel zijn pK_z gegevens verzameld van een aantal zuren. De gegevens zijn voornamelijk afkomstig van de Nederlands-, Engels- en Duitstalige Wikipedia's. In de eerste kolom staan de namen vermeld van de neutrale verbindingen. Heeft een verbinding meerdere ionisatiestappen of groepen, dan staat dit aangegeven, Bij verbindingen met plaats-aanduidingen staat de plaatsaanduiding na een komma. Het voordeel van deze manier van noteren is dat bij sorteren op naamvergelijkbare verbindingen direct na elkaar staan.^[1]

Een aantal van de genoemde zuren wordt ook genoemd in BINAS 5e druk Tabel 49. Indien de pK_z-waarde substantieel verschilt van de in Wikipedia genoemde waarde, staat dit via een evrwijzing aangegeven. Verschillen tot 0.05 pK_z-eenheid worden niet gemeld.
