Kugwiritsa ntchito

Alpha Nephthophyllein imagwiritsidwa ntchito ngati chizindikiro cha acid-base. Ndiwopanda mtundu mpaka wachikasu walalanje pa pH pafupifupi 6.7 ndipo umasintha kuchoka ku lalanje wachikasu kupita ku buluu pa pH yozungulira 7.9. Zodetsedwa muzinthu zomwe zimapezeka pamalonda nthawi zambiri zimawonekera ngati mtundu wofiira wopepuka, womwe umasintha kuchokera kufiira kowala kupita ku buluu wobiriwira pa pH ya 7.3-8.7.
