Fenolphthalein cas 77-09-8 ni iki?

Fenolphthalein ni acide kama idakomeye, igaragara nkibara ryera cyangwa umuhondo mutoya kristu nziza mubushyuhe bwicyumba. Ntabwo ari impumuro nziza kandi ntabwo iryoshye. Biragoye gushonga mumazi ariko byoroshye gushonga muri alcool (Ethanol) na ether. Irashonga mugisubizo cya alcool kugirango ikore aside-ishingiro. Ntibara rifite ibara rya acide na umutuku mubisubizo bya alkali cyangwa umuti wa karubone ya alkali. Ariko, niba iri mubisubizo bya alkali, bizatanga aside trimetallic idafite ibara. umunyu, ibara ry'umutuku rirashira
