Makanekiuma hydroxide. Helu a me ka Nine Inch ka waiwai. Palapala noi.

makanekiuma hydroxide (haʻilula mg (OH) 2) - mea he'okanikaʻole Nine Inch hui, makanekiuma hydroxide ('ākilikai honua metala). Ua pili ia i ka pūʻulu-insoluble kumu.

Helu waiwai o ka makanekiuma hydroxide

1. Malalo o maʻamau rula, makanekiuma hydroxide mea colorless (moakaka) nā pōaka me he hexagonal puka olu oia.
2. decomposes e makanekiuma'okesaside (MgO), a me ka wai (H2O) ma ka wela o ka ekolu haneri a me kanalima degere.
3. absorbs ea mai ke kalapona'okikene lua (CO2) a me ka wai (H2O), ma ia ho okumu i ke kumu o makanekiuma kalepona.
4. kokoke insoluble i ka wai a me ka wailana ma ka 'amoniuma paʻakai.
5. Ke kumu o ka meakino ikaika.
6. Ma ke ano maoli, ia lŘlŘ i loko o ka palapala o ka kūikawā mea pōhaku - brucite.

Pehea e loaa makanekiuma hydroxide?

1. He mea hiki ke loaa ma ka reacting makanekiuma paʻakai me nā alkalies e like me:

MgCl2 (makanekiuma koloriside) + 2NaOH (paʻakai hydroxide) = mg (OH) 2 (precipitated, makanekiuma hydroxide) + 2NaCl (paʻakai koloriside)

Mg (NO3) 2 (makanekiuma nitrate) + 2KOH (potasiuma kumu) = mg (OH) 2 (makanekiuma kumu precipitates) + 2KNO3 (potasiuma nitrate)

2. A, he Nine Inch hui hiki ke loaa ma ka reacting calcined dolomite me ka koloriside (MgCl2) pāʻoihana o ke makanekiuma (CaO * MgO):

MgCl2 (makanekiuma koloriside) + CaO * MgO (calcined dolomite) + 2H2O (ka wai) = 2Mg (OH) 2 (makanekiuma kumu precipitates) + CaCl2 (kalipuna koloriside)

3. honua makanekiuma hiki ke loaa no hoi ma ka naoh o ka wai, ka ohu a me ka mea hao makanekiuma:

Mg (makanekiuma metala) + 2H2O (ka wai mahu) = mg (OH) 2 (precipitated) + h2 (hydrogen i loko o ka palapala o ke kinoea)

Ke Nine Inch waiwai o ka makanekiuma hydroxide:

1. kēia mea ua ma ka wela o ka 350 degere decomposes i makanekiuma'okesaside a me ka wai. Ua nana e like keia naoh:

Mg (OH) 2 (makanekiuma kumu) = MgO (makanekiuma'okesaside) + 2H2O (ka wai)

2. AaOIeIOUIeXAOAaIN me nāʻakika. Ma keia palapala paakai a me ka wai. examples:

Mg (OH) 2 (kumu) + 2HCl (hydrochloricʻakika) = MgCl2 (makanekiuma koloriside) + 2H2O (ka wai)

Mg (OH) 2 (kumu) + H2SO4 (sulfuricʻakika) = MgSO4 (makanekiuma sulufahate) + 2H2O (ka wai)

3. Interfaces me kaʻakika oxides. Ke naoh produces ka paakai a me ka wai:

Mg (OH) 2 (kumu) + SO3 (ka sulfur'okesaside) = MgSO4 (makanekiuma sulufahate) + H2O (ka wai)

4. A ua reacted makanekiuma hydroxide me ka wela i kia mekala 'åkilikai pāʻoihana. Ma keia palapala gidroksomagnezaty. examples:

Mg (OH) 2 + 2NaOH (paʻakai kumu) = Na2 (mg (OH) 4)

Mg (OH) + 2 S (OH) 2 (ka sulfur kumu) = M. (mg (OH) 4)

palapala noi:

- like me ka ai mea hoʻonui, papahana no ka mea paa o ka sulfur dioxide i (SO2). Helu ma lalo o ka hoailona E528;
- like fokulyanta wastewater lapaau;
- e like me ka mea hoʻonui i loko o kekahi mau detergents a like me ka ke keʻena i loko o toothpaste;
- hoohehee maemae au ia o ke kō, a i ka paka makanekiuma'okesaside (MgO);

Special noonoo ua haawiia mai e hana i ka Nine Inch i loko o ke ola kino oihana puolo.

Makanekiuma hydroxide ma ka lapaau

Kēia antacid a me ka laxative Agena hiki o neutralizing i ka paakai (hydrochloric, HCl)ʻakika i loko o ka'ōpū, a emi i ka ha awina o gastric wai. Pela i kanawai o ka makanekiuma hydroxide ua pu e loli AAR a me ka haumāna hypersecretion o hydrochloricʻakika. Nō hoʻi, i kēia waiwai paipai 'ia ka peristalsis a me nā naʻau liʻiliʻi. Laxative 'ana ia lŘlŘ hope ma kahi o 2-6 hola.

Nāʻikepili: maʻi gastritis me ka loa a me ka maʻamau secretion, duodenal ulcer a me gastric discomfort, a epigastricʻeha, heartburn ma hope o momoku a inu kope paha ka waiʻona, a me ka constipation.

Contraindications: Hypersensitivity e makanekiuma hydroxide.

He noteworthy i nā mea maʻi hakuʻala pilikia me, ma hope o ke noi ana o ka makanekiuma waihona ipu e hoʻomōhala gipermagnemiya (a laila ka oi o ka makanekiuma i loko o ke kino).

I hoʻohana 'ia ma ka lapaau algeldrat makanekiuma hydroxide - i kahi mea paahana i ua hoʻohana' ia no ka gastric ulcer, huʻi duodenitis, giperatsidnom gastritis, gastralgia, maʻi pancreatitis, heartburn, hyperphosphatemia, a putrefactive fermentation dipepsii. Kēia lāʻau ua contraindicated i loko o nā mea maʻi me ka hypersensitivity, Alzheimer ka maʻi, i hāpai keiki a me ka umauma-e ai ana.
