Hydroxide magnesium. guryaha jirka iyo kiimikada. Codsiga.

hydroxide magnesium (formula mg (OH) 2) - waa xarunta ah kiimikada imanba, hydroxide magnesium (dhulka la shubay cawaaqib xumadoodu). Waxaa loola jeedaa in saldhigyada group-beelaya ah.

guryaha jirka ah ee hydroxide magnesium

1. Xaaladaha caadiga ah, hydroxide magnesium waa midab (transparent) kiristaalo isagoo daaqaddii hexagonal.
2. decomposes in xabagta magnesium (MgO), iyo biyaha (H2O) heerkulka a of saddex boqol iyo konton digrii.
3. nuuga hawada ka carbon dioxide (CO2) iyo biyo (H2O), oon la xirrira aasaasiga ah carbonate magnesium.
4. Xaqiiqo ahaan beelaya in biyo iyo L. in ammonium cusbada.
5. saldhig ee xoogga dhexdhexaad ah.
6. In dabiiciga ah, waxay dhacdaa qaab macdanta gaar ah - brucite.

Sida loo helo hydroxide magnesium?

1. Qoraalkan waxaa laga heli karaa by ficil cusbada magnesium la alkalies kala duwan sida:

MgCl2 (chloride magnesium) + 2NaOH (hydroxide Sodium) = mg (OH) 2 (aloosnayd, hydroxide magnesium) + 2NaCl (sodium chloride)

Mg (NO3) 2 (amooniyam magnesium) + 2KOH (saldhig potassium) = mg (OH) 2 (saldhig magnesium precipitates) + 2KNO3 (amooniyam potassium)

2. Sidoo kale, xarunta kiimikada laga heli karaa by ficil calcined dolomite la chloride (MgCl2) xal of magnesium (Cao * MgO):

MgCl2 (chloride magnesium) + Cao * MgO (dolomite calcined) + 2H2O (oo biyo ah) = 2Mg (OH) 2 (saldhig magnesium precipitates) + CaCl2 (calcium chloride)

3. magnesium Ground sidoo kale waxaa laga heli karaa by reaction ee uumiga biyaha la magnesium ah macdan ah,

Mg (biraha magnesium) + 2H2O (uumiga biyaha) = mg (OH) 2 (aloosnayd) + H2 (hydrogen qaab gaaska a)

The guryaha kiimikada ee hydroxide magnesium:

1. wax Tani waxa ay ahayd at heerkul ah 350 digrii decomposes galay xabagta magnesium iyo biyo. Waxa ay u muuqataa sida cadaanyo this:

Mg (OH) 2 (salaysan magnesium) = MgO (xabagta magnesium) + 2H2O (oo biyo ah)

2. Isku dhex leh acids. In foomka cusbo iyo biyo this. tusaale:

Mg (OH) 2 (salka) + 2HCl (Aashito) = MgCl2 (chloride magnesium) + 2H2O (oo biyo ah)

Mg (OH) 2 (salka) + H2SO4 (sulfuric acid) = MgSO4 (magnesium sulfate) + 2H2O (oo biyo ah)

3. Interfaces la oxides acidic. falcelinta soo saarta ee cusbo iyo biyo:

Mg (OH) 2 (salka) + SO3 (xabagta baaruud) = MgSO4 (magnesium sulfate) + H2O (oo biyo ah)

4. Sidoo kale hydroxide magnesium waxaa ka jawaabay kulul xal alkali urursan. In foomka gidroksomagnezaty this. tusaale:

Mg (OH) 2 + 2NaOH (saldhig sodium) = Na2 (mg (OH) 4)

Mg (OH) 2 + S (OH) 2 (saldhig baaruud) = Sr (mg (OH) 4)

Codsiga:

- sida daro cuntada ah, loogu talagalay ku qabanaya baaruud dioxide (SO2). Registered hoos E528 calaamada;
- sida daawaynta biyaha wasakhaysan fokulyanta;
- sida daro ah in saabuunta dharka kala duwan iyo sida qayb ka ah in lagu cadaydo,
- turxaan oo sonkor ah iyo in ay soo saaraan xabagta magnesium (MgO);

fiiro gaar ah la siiyo si ay u isticmaalaan oo ah kiimikada warshadaha caafimaadka.

hydroxide Magnesium in daawo

ashito iyo calool jilciye wakiilka Tani waxay awood u neutralizing cusbo ah (Hydrochloric, HCL) acid caloosha iyo yareeyaan dhaqdhaqaaqa casiir gastric. Sayidka saameyn ah kuma laha ee hydroxide magnesium waxaa la socda isbedelka Aar iyo hypersecretion sare ee Aashito. Sidoo kale, walax this kor u peristalsis iyo mindhicirrada kale. tallaabo calool jilciye dhacdaa ka dib markii ku saabsan 2-6 saacadood.

Tilmaamayaasha: gastritis chronic la soo kordha oo caadi ah dheecaan, boog dyspepsia iyo raaxo gastric, ama xanuun gaastari, laab ka dib markii sigaarka la cabo ama kafeega ama khamriga, iyo caloosha oo.

Sababo: diidmo in hydroxide magnesium.

Waxaa xusid mudan in dadka qaba dhibaatooyinka kelyaha, ka dib markii codsiga ah ee salka magnesium waxaa laga yaabaa in la horumariyo gipermagnemiya (i.e. xad dhaaf ah magnesium jirka).

Sidoo kale loo isticmaalaa in daawada algeldrat hydroxide magnesium - aalad in loo isticmaalo boog gastric, duodenitis ba'an, gastritis giperatsidnom, gastralgia, pankreatit chronic, laab, hyperphosphatemia, ama dipepsii halsano putrefactive. daroogada Tani waa u bukaanka qaba diidmo, cudurka Alzheimers, inta ay uurka leedahay ama naas-nuujinta.
