Sinetintfo tekusebenta letisezingeni lelisetulu. Imikhicito yetfu itfunyelwa ngaphandle kwe-USA, e-UK njalonjalo, ijabulela simo lesimangalisako emkhatsini wemakhasimende eFekthri Liquid Glacial Acetic Acid 99.9% ku Bulk Supply, Sitawuwenta konkhe lokusemandleni etfu kuhlangabetana noma kwedlula lokucacisiwe kwemakhasimende ngetisombululo letisezingeni lelisetulu, umcondvo lophakeme, kanye nekuniketa sikhatsi lesisebenta kahle kanye. Siyawemukela onkhe ematfuba.

Imikhicito yetfu itfunyelwa ngaphandle kwe-USA, e-UK njalonjalo, ijabulela simo lesimangalisako emkhatsini wemakhasimende e , Kutsengisa tisombululo tetfu akubangeli bungoti futsi kuletsa inzuzo lesetulu enkampanini yakho esikhundleni saloko. Kuyintfo yetfu lephishekelako njalo kudala linani kumakhasimende. Inkampani yetfu ifuna ema-ejenti ngekwelisciniso. Ulindzeni? Wota uhlanganyele natsi. Nyalo noma ungalokotsi.














Lokucuketfwe yi-Acetic Acid ye-Glacial lesemantini
Umtsetfo: Kulinganisa lokungatsatsi luhlangotsi ngesisombululo lesijwayelekile se sodium hydroxide kusetjentiswa iphenolphthalein njengenkhomba. Lokucuketfwe kwe-Formic acid kuyabanjwa ekubaleni.
Tintfo letisebentako kanye netisombululo:
Sisombululo lesijwayelekile se-sodium hydroxide: c (NaOH) = 1 mol / L.
Inkomba ye-phenolfthalein: 5 g / L sisombululo se-ethanol. Hlanganisa 0.5 g we phenolphthalein ku 100 ml we 95% (V/V) ethanol bese uyanciphisa ngesisombululo se sodium hydroxide lesingu 4 g/L kuze kuvele umbala lopinki lobutsakatsaka.
Tintfo tekusebenta: Libhodlela lekukala le-Conical (3 ml umthamo); burette ye-alkaline (50 ml umthamo).Esidi ye-Acetic ye-Glacial lesemantini.
Inchubo: Kala cishe 2.5 g wesampula ebhodleleni lekukala le conical, lenembile ku 0.0001 g. Faka lelibhodlela eflasikini lelifana ne conical lelingu 250 ml lelicuketse emanti lahlungiwe langena 50 ml. Vula sivalo selibhodlela, faka 0.5 ml wenkomba ye phenolphthalein, bese ufaka ngesisombululo lesijwayelekile se sodium hydroxide kuze kube ngulapho umbala lopinki lobutsakatsaka uphikelela imizuzwane lesihlanu.
