Ke ʻano hana titration waikawa Propionic
E hoʻomākaukau i nā mea aniani e like me ka burette a me ka ʻōmole conical. Ma ka hoʻoholo ʻana i ka nui o ka waikawa propionic i loko o nā huahana waikawa propionic ʻoihana ma ke ʻano he laʻana, e kaupaona pololei i kahi nui o ka hāpana waikawa propionic a waiho i loko o ka ʻōmole conical. E hoʻohui i kahi nui kūpono o ka wai i hoʻoheheʻe ʻia e hoʻoheheʻe loa i ka hāpana. A laila koho i kahi hōʻailona kūpono, e like me ka phenolphthalein. E titrate me kahi hopena maʻamau sodium hydroxide o ka nui i ʻike ʻia. I ka wā o ka titration, hana ʻia kahi hopena neutralization ma waena o ka sodium hydroxide a me ka waikawa propionic. Ke hoʻohui ʻia ka sodium hydroxide, piʻi mālie ka pH o ka hopena. Hiki i ka hopena titration ke hoʻololi ke kala o ka hopena mai ke kala ʻole i ka ʻulaʻula māmā a noho mau no ka hapalua minuke. Ma muli o ka nui o ka hopena maʻamau sodium hydroxide i hoʻopau ʻia, hiki ke helu ʻia ka nui o ka waikawa propionic i loko o ka hāpana me ka hoʻohana ʻana i nā pilina stoichiometric. Loaʻa ke ʻano kikoʻī mai ka hoʻohālikelike kemika kaulike no ka hopena ma waena o ka waikawa propionic a me ka sodium hydroxide, nona ka lakio stoichiometric o 1: 1, i hoʻololi ʻia me ka hoʻohana ʻana i nā ʻano molar concentration a me nā ʻano nui.info@pulisichem.cn

ʻO Shandong Pulisi Chemical Co., Ltd. Hoʻolauna Kūikawā no ka waikawa Propionic
He loea ʻo Shandong Pulisi Chemical Co., Ltd. i ka hoʻolako ʻana a me ka hāʻawi ʻana i ka Propionic Acid CAS 79-09-4 o ka papa ʻoihana a me ka papa meaʻai. Ke hoʻohana nei i ka nānā ʻana i ka hana maʻamau a me nā kaʻina hana kānana maka maka koʻikoʻi, hōʻike kā mākou propionic acid i ka maʻemaʻe kiʻekiʻe, ka haʻahaʻa o ka haumia a me nā waiwai kino a me nā kemika paʻa, e kūlike piha ana me nā kikoʻī ʻoihana a me ka palekana meaʻai o ka honua.
Hoʻohana nui ʻia i ka pale ʻana i ka mildew hānai, ka mālama ʻana i ka meaʻai, ka synthesis waena o nā lāʻau lapaʻau, ka synthesis resin pena a me ka hoʻomākaukau ʻana i nā mea maka kemika i kēlā me kēia lā, ua loaʻa i kā mākou waikawa propionic ka ʻike mākeke paʻa ma Asia Hikina Hema, ka Hikina Waena, ʻEulopa a me nā wahi ʻē aʻe. Ma ka hilinaʻi ʻana i ka ʻōnaehana hoʻokaʻawale logistics piha a me ka hui lawelawe hoʻokuʻu aku kemika ʻoihana, kākoʻo mākou i ka hoʻopili maʻamau, ka hoʻonohonoho kauoha maʻalahi a me ka lako paʻa no ka wā lōʻihi, a hāʻawi mau i nā mea kūʻai aku me nā hoʻonā mea maka kemika kūpono a me ke kākoʻo kūʻai hoʻokahi.
