Sodium chloride

Sodium chloride

Nambala ya CAS: 7647-14-5

Dzina lina: mchere wa patebulo; mchere wa thanthwe

Maina achingerezi: Mchere wamba; Mchere wa patebulo; Mchere wa Roch; Mchere wa m'nyanja

Fomula ya maselo: NaCl

Kulemera kwa maselo: 58.44

Kapangidwe kake: krustalo woyera, wosungunuka m'madzi. Pa 25°C, 1g imasungunuka m'madzi a 2.8ml, 2.6ml madzi otentha, ndi 10ml glycerin, ndipo pafupifupi susungunuka mu ethanol. Kusungunuka kwake m'madzi kumachepa chifukwa cha kukhalapo kwa hydrochloric acid, ndipo pafupifupi susungunuka mu hydrochloric acid yokhazikika. Madzi amadzi ndi osalowerera, okhala ndi pH ya 5.0 ~ 8.0. Kuchulukana kwa 2.17. Malo osungunuka 804℃. Malo owira 1413℃. Mlingo wapakati wakupha (makoswe, omwa) ndi 3.75±0.43g/kg.

Kusungira: kotsekedwa ndi kusungidwa.

gwiritsani ntchito

1. Chotsukira choyezera, chomwe chimagwiritsidwa ntchito poyesa mchere kuti chizindikire kukana dzimbiri kwa chitsulo. Muyezo woyezera siliva nitrate. Kuzindikira pang'ono kwa fluorine ndi silicates. Kuyesa magazi nthawi zonse; kuyesa magwiridwe antchito a chiwindi, ndi zina zotero.

2. Sodium chloride ndi chinthu chofunikira kwambiri chopangira mankhwala, chomwe chimagwiritsidwa ntchito kwambiri m'magawo ambiri monga mankhwala, nsalu, kusindikiza ndi kupaka utoto, labala, chakudya ndi ulimi.

3. Amagwiritsidwa ntchito pokonzekera tris buffer, phosphate buffered saline, MPM-2 (mitotic protein monoclonal 2) cell lysis buffer, immunoprecipitation washing buffer, LB (Luria-Bertani) medium ndi dialysis buffer

4. Amagwiritsidwa ntchito kwambiri popanga mankhwala ndipo amagwiritsidwa ntchito ngati cholowetsa madzi m'njira zosiyanasiyana, chodzaza kapena chophikira m'njira zosiyanasiyana monga mlingo wolimba komanso wochepa, chosungunula mchere m'mankhwala ndi makapisozi, chothandizira kuchitapo kanthu kwachilengedwe, komanso ngati zopangira mankhwala.

5. Mu machitidwe a zamoyo, sodium chloride ndi electrolyte yoyambira yomwe imatha kusintha kuthamanga kwa osmotic, pH balance ndi conductivity. Imagwira ntchito yofunika kwambiri pakusunga kapangidwe ka mapuloteni ndikulimbikitsa ntchito ya ma enzyme. Ndikofunikira pakukhazikitsa kapangidwe ka mapuloteni ndikuyambitsa zochita za biochemical.
