Hydroxide magnesium. meatotino faaletino ma vailaau. Talosaga.

hydroxide magnesium (fuafaatatau Mg (Oi) 2) - o se lotoa vailaau inorganic, magnesium hydroxide (alkaline uamea lalolagi). E faatatau i le nofoaga autu o vaega-insoluble.

meatotino faaletino o hydroxide magnesium

1. I lalo o tulaga masani, o colorless hydroxide magnesium (manino) taʻega tioata i ai o se lattice hexagonal.
2. decomposes e oxide magnesium (MgO), ma le vai (H2O) i se vevela o le tolu selau limasefulu tikeri.
3. absorbs ea mai karaponi carbon (CO2) ma le vai (H2O), lea ua avea ma se faavae carbonate magnesium.
4. O lona insoluble i le vai ma soluble i masima ammonium.
5. O le faavae o le malosi auala.
6. I le natura, o loo tupu i le tulaga o se minerale faapitoa - brucite.

Auala e maua ai hydroxide magnesium?

1. O lenei vaega e mafai ona maua e le tali magnesium masima ma eseese alkalies e pei o:

MgCl2 (chloride magnesium) + 2NaOH (Sodium hydroxide) = Mg (Oi) 2 (precipitated, hydroxide magnesium) + 2NaCl (chloride sodium)

Mg (NO3) 2 (magnesium nitrate) + 2KOH (faavae potassium) = Mg (Oi) 2 (magnesium precipitates faavae) + 2KNO3 (nitrate potassium)

2. foi, e mafai ona maua se lotoa vailaau e le tali calcined dolomite ma chloride (MgCl2) fofo o magnesium (CaO * MgO):

MgCl2 (magnesium chloride) + CaO * MgO (calcined dolomite) + 2H2O (vai) = 2Mg (Oi) 2 (magnesium precipitates faavae) + CaCl2 (chloride kalisiu)

3. E mafai ona maua magnesium Eleele foi i le tali mai a le ausa vai faatasi ma le magnesium apamemea:

Mg (magnesium uamea) + 2H2O (vai ausa) = Mg (Oi) 2 (precipitated) + H2 (hydrogen i le tulaga o se kasa)

Le meatotino vailaau o hydroxide magnesium:

1. O lenei mea sa i ai i se vevela o le 350 tikeri decomposes i oxide magnesium ma le vai. E foliga e pei o lenei tali:

Mg (Oi) 2 (faavae magnesium) = MgO (oxide magnesium) + 2H2O (le vai)

2. fegalegaleaiga ma acids. I lenei pepa masima ma le vai. faataitaiga:

Mg (Oi) 2 (faavae) + 2HCl (acid hydrochloric) = MgCl2 (chloride magnesium) + 2H2O (le vai)

Mg (Oi) 2 (faavae) + H2SO4 (acid sulfuric) = MgSO4 (sulfate magnesium) + 2H2O (le vai)

3. Interfaces ma oxides acidic. O le tali e maua mai o le masima ma le vai:

Mg (Oi) 2 (faavae) + SO3 (oxide teio) = MgSO4 (sulfate magnesium) + H2O (le vai)

4. foi ua tali hydroxide magnesium ma vevela fofo alkali taulai. I totonu o lenei gidroksomagnezaty pepa. faataitaiga:

Mg (Oi) 2 + 2NaOH (faavae sodium) = Na2 (Mg (Oi) 4)

Mg (Oi) 2 + S (Oi) 2 (faavae teio) = Sr (Mg (Oi) 4)

talosaga:

- e avea o se faʻaopoopoga meaai, fuafuaina mo le noatia o karaponi teio (SO2). Faamauina i lalo o le faailoga E528;
- e pei togafitiga suavai leaga fokulyanta;
- e avea o se faʻaopoopoga i detergents eseese ma avea o se vaega i mea fulunifo;
- faamamaina o le suka ma e maua oxide magnesium (MgO);

ua tuuina atu se gauai faapitoa i faaaogaina o le vailaau i le alamanuia soifua maloloina.

Magnesium hydroxide i vailaau faafomai

O lenei sui sooupu antacid ma laxative mafai ona neutralizing a masima (hydrochloric, HCl) acid i le manava ma le faaitiitia o le gaoioiga o le sua o le gastric. O lea e leai se aafiaga o hydroxide magnesium ua tuuina atu faatasi ma suiga AAR ma hypersecretion lona lua o acid hydrochloric. Foi, o lenei mea e uunaia ai peristalsis ma isi loto ona. gaoioiga Laxative tupu ina ua mavae e uiga i le 2-6 itula.

Faailoga: gastritis faaumiumi ma secretion faateleina ma le masani ai, papala duodenal ma faaletonu gastric, po o tiga epigastric, manava tīgā ina ua uma ulaula pe inu kofe po o le ava malosi, ma manava masuasua.

Contraindications: Hypersensitivity e hydroxide magnesium.

E mataʻina e gasegase ma faafitauli fatugao, ina ua uma ona talosaga a le mafai ona atiina ae le faavae magnesium gipermagnemiya (i.e. se faasiliga o magnesium i le tino).

Foi faaaogaina i vailaau algeldrat magnesium hydroxide - o se meafaigaluega ua faaaogāina mo papala gastric, duodenitis matuitui, giperatsidnom gastritis, gastralgia, pancreatitis faaumiumi, manava tīgā, hyperphosphatemia, po putrefactive dipepsii fermentation. ua contraindicated lenei fualaau oona i gasegase ma hypersensitivity, faamaʻi o le Alzheimer, i le taimi o maitaga po o le susu-fafagaina.
