Factory Liquid Glacial Acetic Acid 99.9% mu Kuchuluka Kopezeka
Tili ndi zida zamakono kwambiri. Zogulitsa zathu zimatumizidwa kunja ku USA, UK ndi zina zotero, ndipo makasitomala athu ali ndi udindo wabwino kwambiri chifukwa cha Factory Liquid Glacial Acetic Acid 99.9% mu Bulk Supply. Tidzayesetsa kukwaniritsa kapena kupitirira zomwe makasitomala akufuna pogwiritsa ntchito njira zabwino kwambiri, malingaliro apamwamba, komanso opereka chithandizo ogwira ntchito bwino komanso panthawi yake. Tikulandira makasitomala onse omwe akufuna.
Tili ndi zida zamakono kwambiri. Zogulitsa zathu zimatumizidwa kunja ku USA, UK ndi zina zotero, ndipo makasitomala athu ali ndi udindo wabwino kwambiri. Kugulitsa mayankho athu sikubweretsa zoopsa ndipo kumabweretsa phindu lalikulu ku kampani yanu m'malo mwake. Cholinga chathu nthawi zonse ndi kupangitsa makasitomala kukhala ndi phindu. Kampani yathu ikufuna othandizira moona mtima. Mukuyembekezera chiyani? Bwerani mudzatigwirizane nafe. Tsopano kapena ayi.
Kuchuluka kwa Madzi a Glacial Acetic Acid
Mfundo: Kuchuluka kwa asidi m'thupi pogwiritsa ntchito njira yoyeretsera madzi pogwiritsa ntchito sodium hydroxide pogwiritsa ntchito phenolphthalein ngati chizindikiro. Kuchuluka kwa asidi m'thupi kumachotsedwa mu kuwerengera.
Ma Reagents ndi Mayankho:
Njira yokhazikika ya sodium hydroxide: c(NaOH) = 1 mol/L.
Chizindikiro cha Phenolphthalein: 5 g/L yankho la ethanol. Sungunulani 0.5 g ya phenolphthalein mu 100 ml ya 95% (V/V) ethanol ndikuchepetsa kugwiritsa ntchito 4 g/L yankho la sodium hydroxide mpaka mtundu wa pinki utawonekera.
Chida: Botolo loyezera lozungulira (lita 3 ml); alkaline burette (lita 50 ml). Liquid Glacial Acetic Acid.
Njira Yogwiritsira Ntchito: Yesani pafupifupi 2.5 g ya chitsanzo mu botolo lolemera lokhala ndi mawonekedwe ofanana ndi 0.0001 g. Ikani botolo mu botolo lokhala ndi mawonekedwe ofanana ndi 250 ml lomwe lili ndi 50 ml ya madzi osungunuka opanda carbon dioxide. Tsegulani chivundikiro cha botolo, onjezerani 0.5 ml ya phenolphthalein indicator, ndikuyika ndi sodium hydroxide standard solution mpaka utoto wa pinki utapitirira kwa masekondi asanu.
