nkhani

Mchere wa Sodium (6CI,7CI), ndi inorganic ionic pawiri, mankhwala mawonekedwe NaCl, colorless kiyubiki makhiristo kapena wabwino crystalline ufa, kulawa mchere. Maonekedwe ake ndi kristalo woyera, gwero lake makamaka ndi madzi a m'nyanja, ndilo gawo lalikulu la mchere. Kusungunuka m'madzi, glycerin, kusungunuka pang'ono mu Mowa (mowa), ammonia yamadzi; Insoluble mu hydrochloric acid. Sodium chloride yodetsedwa ndi yonyansa mumlengalenga. [1] ndi bata wabwino, njira yake amadzimadzi ndi ndale, makampani ambiri kutengera njira electrolytic ano zimalimbikitsa sodium kolorayidi njira kubala haidrojeni, klorini ndi caustic koloko (sodium hydroxide) ndi mankhwala mankhwala (omwe amadziwika kuti chlor-alkali makampani) Itha kugwiritsidwanso ntchito kusungunula ore, electrolysis ya chitsulo chosungunula cha sodium chloride crystal chamoyo cha sodium zitsulo), zamankhwala zomwe zimagwiritsidwa ntchito popanga mchere wamthupi, Moyo ukhoza kugwiritsidwa ntchito zokometsera.

Mchere wa sodium (6CI,7CI)katundu wakuthupi

Chiwerengero cha kubweza: 1.378

Kusungunuka kwamadzi: 360 g/L (25 ºC)

Kukhazikika: kukhazikika pansi pamayendedwe abwinobwino komanso kasamalidwe.

Kusungirako zinthu: nyumba yosungiramo katundu kutentha otsika, mpweya wabwino, youma

Mchere wa sodium (6CI,7CI)Kuthamanga kwa nthunzi: 1 mm Hg (865 °C)

Sodium kolorayidi ndi ufa woyera wopanda fungo wopanda fungo. 801 ℃, kuwira mfundo 1465 ℃, pang'ono sungunuka Mowa, propanol, butane, ndi butane pambuyo solubility mu plasma, mosavuta sungunuka m'madzi, madzi solubility 35.9g (chipinda kutentha). Kubalalika kwa NaCl mu mowa kumatha kupanga colloid, kusungunuka kwake m'madzi kumachepetsedwa ndi kukhalapo kwa hydrogen chloride, pafupifupi insoluble mu hydrochloric acid. Palibe fungo, mchere, zosavuta deliquescence. Kusungunuka m'madzi, kusungunuka mu glycerin, pafupifupi osasungunuka mu ether [3].

Mapangidwe a maselo

Makhiristo a sodium chloride amapanga steric symmetry. Mu mawonekedwe ake a kristalo, ayoni akuluakulu a kloridi amapanga zodzaza kwambiri ndi cubic, pomwe ma ion ang'onoang'ono a sodium amadzaza malo octahedral pakati pa ayoni a kloridi. Ion iliyonse imazunguliridwa ndi ma ion ena asanu ndi limodzi. Kapangidwe kameneka kamapezekanso muzinthu zina zambiri ndipo amatchedwa mawonekedwe amtundu wa sodium chloride kapena kapangidwe ka mchere wamwala.
