Nā waiwai: ke aniani keʻokeʻo, hiki ke hoʻoheheʻe ʻia i ka wai. Ma 25 ° C, hiki ke hoʻoheheʻe ʻia ka 1g i ka wai 2.8ml, 2.6ml wai paila, a me 10ml glycerin, a aneane hiki ʻole ke hoʻoheheʻe ʻia i ka ethanol. Ho'emi 'ia kona solubility i loko o ka wai ma muli o ka waika hydrochloric, a 'ane'ane hiki 'ole ke ho'ohehe'e 'ia i ka waika hydrochloric concentrated. He kūʻokoʻa ka wai wai, me ka pH o 5.0 ~ 8.0. Māmā pili 2.17. Ka helu hehee 804 ℃. Ka helu hoʻolapalapa 1413 ℃. ʻO ka nui o ka make make (iole, waha) he 3.75±0.43g/kg.

Waihona: hoʻopaʻa ʻia a mālama ʻia.

hoʻohana

1. Analytical reagent, hoʻohana ʻia no ka hoʻāʻo ʻana i ka paʻakai paʻakai e ʻike i ke kūpaʻa corrosion metala. He maʻamau no ke ana ʻana i ka nitrate kālā. Microdetermination o ka fluorine a me ka silicates. Nā hoʻāʻo koko maʻamau; nā ho'āʻo hana ate, etc.

2. ʻO ka sodium chloride he mea waiwai nui kemika, hoʻohana nui ʻia i nā kula he nui e like me ka lāʻau lapaʻau, textiles, paʻi a me ka hoʻoluʻu ʻana, ka ʻōpala, ka meaʻai a me ka mahiʻai.

3. Hoʻohana ʻia e hoʻomākaukau i ka tris buffer, phosphate buffered saline, MPM-2 (mitotic protein monoclonal 2) cell lysis buffer, immunoprecipitation washing buffer, LB (Luria-Bertani) medium a me dialysis buffer

4. Hoʻohana nui ʻia ia i ka hoʻomākaukau lāʻau lapaʻau a hoʻohana ʻia ma ke ʻano he penetrant i loko o nā ʻano wai wai, kahi mea hoʻopihapiha a i ʻole ka mea hoʻopili i loko o nā ʻano paʻa paʻa a me nā ʻano semi-solid dosage, kahi diluent i ka paʻakai ʻana i nā lāʻau lapaʻau a me nā capsules, kahi mea hoʻonaninani kūlohelohe. a me kahi mea lāʻau lapaʻau.

5. I loko o nā ʻōnaehana olaola, ʻo ka sodium chloride kahi electrolyte maʻamau e hiki ke hoʻoponopono i ke kaomi osmotic, ke kaulike pH a me ka conductivity. He kuleana koʻikoʻi ia i ka mālama ʻana i ka ʻōnaehana protein a me ka hoʻoikaika ʻana i ka hana enzyme. He mea nui ia no ka hoʻopaʻa ʻana i ka conformation protein a me ka catalyzing i nā hopena biochemical. koʻikoʻi.
