Regel 1:
== pH-indicatoren ==
In onderstaande lijst is een overzicht verzameld van pH-indicatoren. Veel van deze stoffen worden zelden gebruikt, maar kunnen in speciale gevallen uitkomst bieden. In onderstaande tabel zijn gegevens uit meerdere bronnen samengevoegd.<ref name = "Binas">{{BINAS5 | Tabel = 52}}</ref><ref name = "pH-meter">http://www.ph-meter.info/pH-measurements-indicators</ref> Hoewel de gegevens in essentie parallel lopen, zijn er soms kleine verschillen. In die gevallen staan beide waarden vermeld, met de bron waaruit ze betrokken zijn. Staat in een van de kolommen één getal en in de andere twee, dan zijn de bronnen in het eerste geval eensluidend, in het tweede niet.
