Factory Liquid Glacial Acetic Acid 99.9% eka Mphakelo wa Xitalo
Hi na switirhisiwa swa xiyimo xa le henhla. Switirhisiwa swa hina swi rhumeriwa ehandle eka USA, UK na swin’wana, hi tiphina hi xiyimo xo hlamarisa exikarhi ka tiklayenti ta Factory Liquid Glacial Acetic Acid 99.9% eka Mphakelo wa Vunyingi, Hi ta endla leswikulu swa hina ku fikelela kumbe ku tlula swihlawulekisi swa vaxavi hi swintshuxo swa khwalithi ya le henhla, mhaka ya xiyimo xa le henhla, na muphakeri loyi a tirhaka kahle na hi nkarhi. Hi amukela ntshembo hinkwawo.
Hi na switirhisiwa swa xiyimo xa le henhla. Switirhisiwa swa hina swi rhumeriwa eUSA, UK na swin’wana, hi tiphina hi xiyimo xo hlamarisa exikarhi ka tiklayenti for , Ku xavisa swintshuxo swa hina a swi vangi makhombo naswona swi tisa mbuyelo wa le henhla eka khamphani ya wena ematshan’wini ya sweswo. I ku hlongorisa ka hina loku nga cincekiki ku tumbuluxa nkoka eka tiklayenti. Khamphani ya hina yi lava vayimeri hi mbilu hinkwayo. Xana u yimele yini? Tana u ta hi joyina. Sweswi kumbe ku nga ri khale.
Nhlayo ya Acetic Acid ya Glacial ya Mati
Nsinya wa nawu: Neutralization titration hi sodium hydroxide standard solution hiku tirhisa phenolphthalein tani hi xikombiso. Nhlayo ya formic acid yi susiwa eka xibalo.
Switirhisiwa na Switshuxo:
Nkatsakanyo wa ntolovelo wa sodium hydroxide: c(NaOH) = 1 mol/L.
Xikombiso xa phenolphthalein: 5 g/L ya xitofu xa ethanol. N’okisa 0.5 g ya phenolphthalein eka 100 ml ya 95% (V/V) ethanol kutani u neutralize hi 4 g/L sodium hydroxide solution kufikela loko ku humelela muhlovo wa pink wo olova.
Xitirhisiwa: Bodlhela ro pima ra khoni (3 ml ya vuswikoti); alkaline burette (50 ml ya vuswikoti).Asidi ya Glacial ya mati ya Acetic Acid.
Maendlelo: Pima kwalomu ka 2.5 g ya xikombiso eka bodlhela ro pima ra conical, leri kongomeke kuya eka 0.0001 g. Veka bodlhela eka 250 ml ya conical flask leyingana 50 ml ya mati ya distilled lawa yangariki na carbon dioxide. Pfula xifunengeto xa bodlhela, chela 0.5 ml ya phenolphthalein indicator, kutani u titrate hi sodium hydroxide standard solution kufikela loko muhlovo wa pink wo olova wu tshama kuringana 5 wa tisekoni.
