I roto i te ao whakamiharo o te matū, he rite te phenolphthalein ki tētahi wairua ngaro, ataahua hoki, me tōna āhua ahurei me te whānuitanga o ngā whakamahinga, ā, ka noho hei mea nui i roto i ngā mara maha.
Ahakoa te āhua noa o te Phenolphthalein, he paura tioata pai, he mā, he kōwhai rānei te āhua, he āhua noa iho, engari he āhuatanga matū makutu kei roto. He wairewa pakupaku ki te wai matao engari ka taea te totoro noa i tōna āhua i roto i ngā whakarewa rauropi pērā i te etanoru me te etera. Ā, ko te mea e tino mōhiotia ana ko tana mahi tino pai hei tohu waikawa-pūtake. Ina kei raro iho i te 8.2 te uara pH o te otinga, ka noho puku te phenolphthalein, ā, ka puta te wairewa kāore he tae. Heoi, ina peke te uara pH ki te awhe o te 8.2 ki te 10.0, ka "hurihuri" tonu te phenolphthalein, ka puāwai te wairewa me te tae māwhero ataahua, me te mea kei te kanikani ataahua i runga i te atamira matū, e kawe ana i ngā mōhiohio matua o te waikawa, te kawakore rānei o te wairewa ki te tangata mā te huringa tae. I roto i ngā whakamātautau titration waikawa-pūtake, he "kaiwhakawa" tika ake. Whakaarohia mēnā me ine koe i te kukū o tētahi waikawa, pūtake rānei kāore i te mōhiotia, ka tāpirihia e koe ētahi pata o te phenolphthalein. I te haere tonu o te titration, ko te huringa ohorere o te tae o te otinga e tohu tika ana i te mutunga o te titration, e āwhina ana i a koe ki te whiwhi hua whakamātautau tika. He whānui rawa ngā whakamahinga o te Phenolphthalein. I roto i te umanga rongoā, i whakamahia i mua hei rongoā whai hua mō te mate puku. Mā te whakaoho i te plexus io i roto i te pakitara whekau me te whakatairanga i te peristalsis o te uaua maeneene whekau, i āwhina i te tangata ki te whakaoti rapanga whekau. I roto i te ao o te hanga rauropi, he mahi nui tā te phenolphthalein, e whai wāhi ana ki te hanga kirihou, inā koa ko ngā polymers diazazone polyaryletherketone mahi-teitei. Ko ngā muka, ngā paninga me ngā rauemi hiato i hangaia mai i aua polymers kua kitea tā rātou whakamahinga i roto i ngā mara teitei pēnei i te hikohiko me ngā taputapu hiko, ngā taputapu miihini, te kawe waka, te rererangi, te miihini pūngao atomika me te ope taua, nā te mea he pai te ātete ki te wera, te ātete ki te wai, te ātete ki te waikura matū, te ātete ki te koroheketanga wera me te pai o te tukatuka me te hanga.
Kua tāpirihia hoki e te Phenolphthalein te nui o te harikoa ki ō tātou oranga. I roto i te whakaaturanga pūtaiao whakamere, ko te āhuatanga makutu o te "wai e huri ana i te tae" e kiia ana ko te phenolphthalein. I roto i ētahi taonga takaro makutu, ko te āhuatanga o te phenolphthalein e huri ana i te tae ina pāngia e te waikawa, e te kawakore rānei, ka whakamahia hei hanga i ngā pānga tirohanga whakamiharo. Heoi anō, mā ngā mahi ngāwari, ka taea hoki e tātou te hanga pepa whakamātautau phenolphthalein mā tātou anō. Mā te whakamahi hei kimi i ngā matū kawakore, ka whero ina pāngia e te kawakore. Ahakoa he iti noa te haukini i te rangi, ka taea tonu e te pepa whakamātautau makuku te whakaatu i te tae whero mārama.
I te whakamahinga o te phenolphthalein, me tiaki pai hoki tātou i tō tātou ake haumaru. Kia pai te whakahaere i te kukū. Ko te tikanga, ko te otinga waipiro 0.1% te mea tino pai. Āta karohia te pā tata ki te kiri. Ki te pā kino mai, me horoi tonu ki te wai ma. I te wā e rongoa ana, waiho ki te wāhi hauhautanga, maroke hoki, kia matara atu i te rā tika.
Ahakoa tōna iti, he mahi nui tā te Phenolphthalein, he mea makutu tēnei i roto i te ao matū. Ahakoa he tautoko i te rangahau pūtaiao, he whakaora rānei i ngā wheako whakamiharo, ka whakapau kaha ia. Kia mihi tātou ki tēnei "toa" kua mahi puku nei. I te huarahi o te tūhura i ngā mea ngaro.Ngā akoranga o te matū, kia tīmata tātou i ētahi atu upoko whakamiharo me te phenolphthalein!
