He aha te Phenolphthalein CAS 77-09-8?

He waikawa waro ngoikore te Phenolphthalein, e puta mai ana he tioata ma, he kōwhai paku rānei i te pāmahana rūma. Kāore he kakara, kāore hoki he reka o te Phenolphthalein 77-09-8. He uaua te rewa o te Phenolphthalein 77-09-8 ki te wai, engari he ngāwari ki te rewa ki te waipiro (ethanol) me te ether. Ka rewa te Phenolphthalein ki te wai waipiro hei hanga i tētahi tohu waikawa-pūtake. Kāore he tae o te Phenolphthalein 77-09-8 i roto i te wai waikawa, ā, he whero i roto i te wai alkali, i te wai kāponāte konutai konutai rānei. Heoi, ki te mea kei roto i te wai alkali kukū, ka puta he waikawa trimetallic kore tae. Ka memeha te tote, ka memeha te tae whero.

1. Ngā rauemi mata rongoā mō te umanga rongoā: he pai mō te mate puku auau me te mate puku uaua, e wātea ana i roto i ngā papa, i ngā suppositories me ētahi atu momo inenga.

2. Te paura phenolphthalein e whakamahia ana i roto i te hanga rauropi: ko te paura phenolphthalein e whakamahia ana mō ngā kirihou hangai, inā koa mō te hanga i ngā polymer naphthyridine polyaryl ether ketone polyaryl ether ketone. He tino pai te ātete wera, te ātete wai, me te ātete matū o tēnei momo polymer. Nā tōna ātete waikura, tōna ātete koroheketanga wera me te pai o te tukatuka me te hanga, ka tere te whakamahi whānuitia ngā muka, ngā paninga me ngā rauemi hiato i hangaia mai i a ia i roto i ngā taputapu hiko, ngā taputapu miihini, me te kawe waka.

3. Ko te phenolphthalein e whakamahia ana hei tohu waikawa-pūtake, hei tohu mō te titration o ngā otinga kore-wai, me te matū mō te tātari chromatography.
