O le ā le Phenolphthalein CAS 77-09-8?

O le Phenolphthalein o se acid organic vaivai, e foliga mai o ni kristala manifinifi paʻepaʻe pe samasama teisi i le vevela o le potu. O le Phenolphthalein 77-09-8 e leai se manogi ma e leai foʻi se tofo. E faigata ona faʻasusu le Phenolphthalein 77-09-8 i le vai ae faigofie ona faʻasusu i le ava malosi (ethanol) ma le ether. E faʻasusu le Phenolphthalein i le vailaʻau ava malosi e fai ai se faʻailoga acid-base. E leai se lanu o le Phenolphthalein 77-09-8 i le vailaʻau acidic ma mumu i le vailaʻau alkali poʻo le vailaʻau alkali metal carbonate. Peitaʻi, afai o loʻo i totonu o le vailaʻau alkali faʻapitoa, o le a maua ai le trimetallic acid e leai se lanu. masima, e mou atu le lanu mumu

Talosaga

1. Mea fa'afoma'i mo le alamanuia fa'afoma'i: talafeagai mo le manava tata masani ma le faigata ona manava, e maua i papamaa, suppositories ma isi ituaiga vaila'au.

2. Phenolphthalein e faʻaaogaina i le gaosiga o mea ola: o le pauta phenolphthalein e masani ona faʻaaogaina mo palasitika faʻapitoa, aemaise lava mo le gaosiga o le naphthyridine polyaryl ether ketone polyaryl ether ketone polymers. O lenei ituaiga polymer e matua teteʻe atu i le vevela, teteʻe atu i le vai, ma teteʻe atu i vailaʻau. Ona o lona teteʻe atu i le ele, teteʻe atu i le vevela ma le lelei o le faʻagasologa ma le fausiaina, o alava, ufiufi ma mea tuʻufaʻatasi e faia mai ai e vave ona faʻaaogaina lautele i masini eletise, masini faʻainisinia, felauaiga.

3. Phenolphthalein e fa'aaogaina o se fa'ailoga o le acid-base, fa'ailoga mo le titration o vaila'au e le o ni vai, ma se reagent mo le au'ili'iliga o chromatographic.
