Sodium chloride

Sodium chloride

Nhamba yeCAS: 7647-14-5

Alias: tafura yemunyu; rock salt

Chirungu aliases: Common salt; Tafura munyu; Roch munyu; Gungwa munyu

Molecular formula: NaCl

Molecular uremu: 58.44

Zvivakwa: white crystal, soluble mumvura. Pa25°C, 1g inonyungudika mumvura 2.8ml, 2.6ml mvura iri kufashaira, uye 10ml glycerin, uye inenge isinganyungudike mu ethanol. Kunyungudika kwayo mumvura kunoderedzwa nekuvapo kwe hydrochloric acid, uye inenge isingagadziriswi mu concentrated hydrochloric acid. Iyo aqueous solution haina kwayakarerekera, ine pH ye5.0 ~ 8.0. Relative density 2.17. Melting point 804 ℃. Boiling point 1413 ℃. Iyo yepakati inouraya dose (gonzo, remuromo) i3.75±0.43g/kg.

Kuchengetedza: yakavharwa uye yakachengetwa.

use

1. Analytical reagent, inoshandiswa pamunyu wekupfapfaidza bvunzo kuona simbi inomira. Chiyero chekuyera silver nitrate. Microdetermination yefluorine uye silicates. Kuongororwa ropa nguva dzose; chiropa kushanda miedzo, nezvimwewo.

2. Sodium chloride inokosha inokosha kemikari mbishi zvinhu, inoshandiswa zvakanyanya muminda yakawanda yakadai semishonga, machira, kudhinda uye dhayi, rabha, chikafu nekurima.

3. Inoshandiswa kugadzira tris buffer, phosphate buffered saline, MPM-2 (mitotic protein monoclonal 2) cell lysis buffer, immunoprecipitation washing buffer, LB (Luria-Bertani) yepakati uye dialysis buffer.

4. Inoshandiswa zvakanyanya mukugadzirira kwemishonga uye inoshandiswa seinopinza mune yemvura dosage mafomu, filler kana coating agent mune yakasimba dosage mafomu uye semi-solid dosage mafomu, diluent mukuita salting kunze kwemishonga uye capsules, organic reaction catalyst, uye mishonga mbishi zvinhu.

5. Muzvinyorwa zvehupenyu, sodium chloride ndiyo electrolyte inokosha inogona kugadzirisa osmotic pressure, pH balance uye conductivity. Inoita basa rakakosha mukuchengetedza chimiro cheprotein uye kusimudzira basa re enzyme. Izvo zvakakosha pakudzikamisa protein conformation uye catalyzing biochemical reactions. crucial.
