    Phenolphthaleinhe waikawa waro ngoikore, ka puta he kiripiri ma, he kowhai paku ranei i te pāmahana rūma. He hongi me te kore reka. He uaua ki te memeha i roto i te wai engari he ngawari ki te wairewa ki te waipiro (waihā) me te etera. Ka rewa ki roto i te wairewa waipiro hei tohu tohu waikawa-waahi. Karekau he tae i roto i te wairewa waikawa me te whero i roto i te wairewa kawakore, i te wairewa warowaiwa whakarewa alkali ranei. Heoi, mena kei roto i te wairewa kawakore, ka puta he waikawa trimetallic kore tae. te tote, ka memenge te tae whero

    1. Ko nga rauemi mata rongoa mo te umanga rongoa: e tika ana mo te kookiri kawa me te whakakeke, e waatea ana i roto i nga papa, nga suppositories me etahi atu momo inenga.

    2. Phenolphthalein whakamahia i roto i te whakahiato waro: te nuinga whakamahia mo te kirihou waihanga, ina koa mo te whakahiato o naphthyridine polyaryl ether ketone polyaryl ether ketone polymers. Ko tenei momo polymer he tino pai te parenga wera, te aukati wai, me te aukati matū. Na te kaha o te waikura, te wera o te koroheketanga me te pai o te tukatuka me te hangai, ka tere te whakamahi i nga muka, paninga me nga rauemi hiato mai i a ia i roto i nga taputapu hiko, taputapu miihini, kawe waka, aerospace, miihini hiko ngota me nga mara hoia.

    3. Ka whakamahia te Phenolphthalein hei tohu waikawa-papa, tohu mo te titration o nga wairewa kore-wai, me te reagent mo te tātari chromatographic.
