Isicelo

I-Alpha Nephthophyllein isetshenziswa njengenkomba ye-acid-base. Ayinambala ukuya kokuphuzi okusawolintshi ku-pH ecishe ibe ngu-6.7 futhi ishintsha isuka kowolintshi ephuzi ibe luhlaza okwesibhakabhaka ku-pH ecishe ibe ngu-7.9. Ukungcola emikhiqizweni ethengiswayo kuvame ukuvela njengombala obomvu okhanyayo, oshintshayo ukusuka kokubomvu ngokukhanyayo ukuya kokuluhlaza okwesibhakabhaka nokuluhlaza ku-pH engu-7.3-8.7.
