Isicelo

I-Alpha Nephthophyllein isetshenziswa njengesibonakaliso se-acid-base. Ayinambala kuya kophuzi ophuzi ku-pH engaba ngu-6.7 futhi ishintsha kusuka kophuzi ophuzi kuya koluhlaza okwesibhakabhaka ku-pH engaba ngu-7.9. Ukungcola emikhiqizweni ethengiswayo kuvame ukubonakala njengombala obomvu okhanyayo, oshintsha kusuka kobomvu okhanyayo kuya koluhlaza okwesibhakabhaka ku-pH engaba ngu-7.3-8.7.
