Mankhwala enaake a hydroxide. Thupi ndi mankhwala katundu. Ntchito.

mankhwala enaake a hydroxide (chilinganizo mg (o) 2) - ndi zochita kupanga mankhwala pawiri, magnesium hydroxide (zamchere lapansi zitsulo). Zimatanthauza zapansi gulu-insoluble.

thupi katundu wa hydroxide mankhwala enaake a

1. Pa zinthu zachilendo, magnesium hydroxide ndi colorless (mandala) timibulu kukhala latisi hexagonal.
2. linawola kuti okusayidi mankhwala enaake a (MgO), ndi madzi (H2O) pa kutentha kwa madigiri mazana atatu makumi asanu.
3. zimatenga mpweya wa carbon dioxide (CO2) ndi madzi (H2O), potero kupanga zofunika mankhwala enaake a carbonate.
4. Pafupifupi insoluble m'madzi ndi sungunuka salt ammonium.
5. m'munsi mwa mphamvu sing'anga.
6. chikhalidwe, limapezeka mu mawonekedwe a mchere wapadera - brucite.

Kodi kupeza mankhwala enaake a hydroxide?

1. chuma amenewa mukhonza kuwapeza mwa kuchita salt mankhwala enaake a ndi alkalies zosiyanasiyana monga:

MgCl2 (magnesium mankhwala enaake) + 2NaOH (sodium hydroxide) = mg (o) 2 (woterowu, magnesium hydroxide) + 2NaCl (sodium kolorayidi)

Mg (NO3) 2 (magnesium nitrate) + 2KOH (m'munsi potaziyamu) = mg (o) 2 (magnesium m'munsi precipitates) + 2KNO3 (potaziyamu nitrate)

2. Komanso, pawiri mankhwala akhoza analandira mwa kuchita calcined dolomite ndi mankhwala enaake (MgCl2) yankho ya magnesium (CaO * MgO):

MgCl2 (magnesium mankhwala enaake) + CaO * MgO (calcined dolomite) + 2H2O (madzi) = 2Mg (o) 2 (magnesium m'munsi precipitates) + CaCl2 (kashiamu kolorayidi)

3. Ground mankhwala enaake a akhoza kuwapeza komanso zimene nthunzi ya madzi ndi mankhwala enaake a zachitsulo:

Mg wa (magnesium zitsulo) + 2H2O (nthunzi ya madzi) = mg (o) 2 (woterowu) + H2 (haidrojeni mu mawonekedwe a mafuta a)

The katundu mankhwala hydroxide mankhwala enaake a:

1. Zinthu zimenezi anali pa kutentha madigiri 350 amaola mu okusayidi mankhwala enaake a ndi madzi. Izo zikuwoneka ngati anachita izi:

Mg (o) 2 (magnesium maziko) = MgO (magnesium okusayidi) + 2H2O (madzi)

2. mogwirizana ndi zidulo. Mu mchere mawonekedwe ndi madzi. zitsanzo:

Mg (o) 2 (m'munsi) + 2HCl (hydrochloric acid) = MgCl2 (magnesium mankhwala enaake) + 2H2O (madzi)

Mg (o) 2 (m'munsi) + H2SO4 (asidi sulfuric) = MgSO4 (magnesium sulfate) + 2H2O (madzi)

3. polumikizira ndi oxides acidic. Zimene ambabala mchere ndi madzi:

Mg (o) 2 (m'munsi) + SO3 (okusayidi sulfure) = MgSO4 (magnesium sulfate) + H2O (madzi)

4. Ndiponso hydroxide mankhwala enaake a ali anachitira ndi otentha anaikira njira soda. Mu ichi gidroksomagnezaty mawonekedwe. zitsanzo:

Mg (o) 2 + 2NaOH (sodium wochuluka m'munsi) = Na2 (mg (o) 4)

Mg (o) 2 + S (o) 2 (sulfure m'munsi) = SR (mg (o) 4)

ntchito:

- monga zowonjezera chakudya, anaikira kumangako wa woipa sulfure (SO2). Mwalamulo pansi pa E528 chizindikiro;
- ngati mankhwala fokulyanta madzi ogwiritsidwa ntchito;
- monga zowonjezera mu detergents zosiyanasiyana ndipo ndi mbali mu mankhwala otsukira mano;
- kuyenga shuga ndi kubala mankhwala enaake a okusayidi (MgO);

mwapadera wapatsidwa ntchito ya mankhwala mu makampani chisamaliro chaumoyo.

Mankhwala enaake a hydroxide mankhwala

Izi mankhwala ochotsa asidi ndi mankhwala ofewetsa tuvi tolimba wothandizila angathe neutralizing mchere (hydrochloric, HCl) asidi m'mimba ndi kuchepetsa ntchito ya madzi muzituluka. Choncho palibe zotsatira za hydroxide mankhwala enaake a limodzi ndi kusintha AAR ndi hypersecretion yachiwiri ya acid amathiridwa. Komanso, mankhwala amalimbikitsa peristalsis ndi matumbo ena. kanthu mankhwala ofewetsa tuvi tolimba zikadzatha za 2-6 maola.

Zikuonetsa: aakulu gastritis ndi chodziwa ndi wabwinobwino katulutsidwe, mmatumbo chilonda ndi chapamimba kusamva, kapena ululu epigastric, kutentha pambuyo kusuta kapena kumwa khofi kapena mowa, ndi kudzimbidwa.

Contraindications: Hypersensitivity kuti hydroxide magnesium.

N'zochititsa chidwi kuti odwala matenda a impso, pambuyo ntchito m'munsi mankhwala enaake a angathe gipermagnemiya (i.e. ndi muyeso ya magnesium mu thupi).

Ntchito mankhwala algeldrat mankhwala enaake a hydroxide - chida kuti ntchito chapamimba chilonda, pachimake duodenitis, giperatsidnom gastritis, gastralgia, kapamba aakulu, kutentha, hyperphosphatemia, kapena putrefactive nayonso mphamvu dipepsii. Izi mankhwala contraindicated odwala ndi hypersensitivity, matenda a Alzheimer, pa mimba kapena mukuyamwitsa.
