Wamkelekile abathengi basekhaya nakwamanye amazwe ukuba baqhagamshelane kwaye babuze!
Izixhobo eziqhutywa kakuhle, iqela lokuthengisa elinobuchule, kunye neenkampani eziphuculiweyo emva kokuthengisa; Sikwangamalungu amakhulu osapho adibeneyo, wonke umntu unamathela kwinzuzo yombutho "umanyano, ukuzinikela, ukunyamezelana" , Ngokudibanisa imveliso kunye namacandelo orhwebo lwangaphandle, sinokubonelela ngezisombululo ezipheleleyo zabathengi ngokuqinisekisa ukuhanjiswa kwezinto ezifanelekileyo kwindawo elungileyo ngexesha elifanelekileyo, okuxhaswa ngamava ethu amaninzi, amandla okuvelisa anamandla, umgangatho ohambelanayo, iipotifoliyo zemveliso ezahlukeneyo kunye nolawulo lwendlela yoshishino kunye neenkonzo zethu ezivuthiweyo ngaphambi nasemva kokuthengisa. Singathanda ukwabelana ngezimvo zethu nawe kwaye samkele izimvo zakho kunye nemibuzo yakho.
I-ThymolphthaleinIgama lesayensi le-“3,3-bis(4-hydroxy-5-isopropyl-2-methylphenyl)-phthalide”, eyi-reagent yendalo. Ifomyula yekhemikhali yi-C28H30O4, kwaye ubunzima be-molecular yi-430.54. Yipowder emhlophe ekristale. Inyibilika lula kwi-ether, i-acetone, i-sulfuric acid kunye nezisombululo ze-alkaline, kwaye ayinyibiliki emanzini. Ihlala isetyenziswa njengesalathisi se-acid-base, kwaye uluhlu lwayo lotshintsho lombala lwe-pH yi-9.4-10.6, kwaye umbala uyatshintsha ukusuka kokungenambala ukuya koluhlaza okwesibhakabhaka. Xa isetyenziswa, idla ngokulungiswa ibe yisisombululo se-ethanol esingu-0.1% 90%. Ikwalungiswa nezinye izalathisi ukwenza isalathisi esidibeneyo esithambileyo ukwenza uluhlu lwayo lotshintsho lombala lube mxinwa kwaye ukubonwa kucace ngakumbi.

I-Thymolphthalein idla ngokusetyenziswa njengesalathisi se-asidi, enoluhlu lotshintsho lombala lwe-pH oluyi-9.4 ukuya kwi-10.6, kunye notshintsho lombala ukusuka kokungenambala ukuya koluhlaza okwesibhakabhaka. Xa isetyenziswa, idla ngokulungiswa njengesisombululo se-ethanol esingu-0.1% 90%, kwaye idla ngokuxutywa nezinye izibonakaliso ukwenza isalathisi esixutyiweyo ukwenza uluhlu lwayo lotshintsho lombala lube mxinwa kwaye lucace ngakumbi ukuba lubonwe. Umzekelo, isalathisi esenziwe ngokuxuba isisombululo se-ethanol esingu-0.1% sale reagent kunye nesisombululo se-ethanol esingu-0.1% se-phenolphthalein asinambala kwisisombululo se-asidi, simfusa kwisisombululo se-alkaline, kwaye sinyuka kwi-pH 9.9 (indawo yokutshintsha kombala), okulula kakhulu ukuyibona.
Iimveliso zipakishwe ebhegini, 25kg/idrum
