Hydroxide sodium, hantida jidh ahaaneed iyo kiimikada:

hydroxide Sodium, ama Soodhaha - xarunta imanba oo iska leh fasalka ka mid ah saldhigyada ama hydroxides. Sidoo kale ee farsamo iyo dibadda walax this yeedhay Soodhaha. Magaca Common - Soodhaha - waxay ahayd sabab u tahay tallaabo xoqe xoog leh.

Tani walax crystalline cad adag isagoo hygroscopicity, barafka at 328 digrii. hydroxide sodium waa diyaar milma biyaha iyo waa elektrolytka xoog leh. Marka dissociation la jeexo Ayaa galay waxbarashada bir ah iyo udhigo hydroxide.

Marka diridda biyo foomamka xarunta firfircoon - alkali - dareento oo saabuun leh. reaction Tani baxa aad u degdeg ah - la buufiyo iyo kulaylkii. Waxaa ku dhacay iyo dhamayta maqaarka iyo xub-axaleedka keena gubashada kiimiko u daran, sidaa darteed marka aad ka shaqayso, waa in aad ka taxadartaa iyo ilaaliso gacmahaaga iyo indhahaaga. Ka dib markii xiriir la walax si epithelium ama indhaha, afka, waxaa lagama maarmaan ah sida ugu dhakhsaha badan waxaa laga yaabaa in meelaha ay saameeyeen biyo ha ku maydho iyo xal daciif ah acetic (2%) ama boron (3%) ee acid ah, ka dibna mar kale biyo. Ka dib markii gargaarka degdegga ah dhibbanayaasha bixinta u baahan tahay inaad aragto dhakhtar.

hydroxide sodium (formula kiimikada ee xarunta - NaOH, struturnaya - NaOH) - walax kiimikaad ahaan firfircoon, taas oo dhici karta inay labada imanba iyo walxaha organic. waxaa lagu ogaan in ay xal aqueous doonaa tayo reaction in ra'iyi hydroxide leh noocyo kala duwan oo tilmaamayaasha. Sayidka, tilmaame buxo noqdo buluug mugdi ah, orange methyl - huruud ah, iyo phenolphthalein - miro guduud, kuna waari dhexdeeda xoogga midabka ku xirnaan doontaa fiirsashada of alkali.

sodium geli Gidrksid galay fal-celin sida:

1. dhexdhexaadnimada leh acids, oxides acid iyo xeryahooda amphoteric. Natiijada reaction tani waa formation of biyaha iyo gidroksokompleka cusbo ama - in ay dhacdo fal-celin iyo saldhigyadooda, iyo oxides amphoteric;

2. sarrifka la cusbada,

3. la Biraha kuwaas oo isku xigta si ay u hydrogen elektorhimichesky Beketova oo ay leeyihiin iman kara hooseeyo;

4. a non-birta iyo halogens;

4. esters hydrolysis;

5. saponification la dufanka (sameeyay saabuun iyo glycerin);

6. reaction la alcohols (alkoxides soo saaray walax).

Sidoo kale qaab la shubay Soodhaha burburin kara galaas oo muraayad, iyo joogitaanka oxygen - biraha sharaf leh (platina).

hydroxide sodium in loo diyaar garoobo laga yaabaa by hababka:

1. electrolysis ee aqueous NaCl (hab diaphragm iyo xuub)
2. kiimikada (lime iyo habka ferrite).

Sanadihii la soo dhaafay, hababka inta badan la isticmaalo waxay ku salaysan yihiin electrolysis, maxaa yeelay, iyagu waa faa'iido dheeraad ah.

Soodhaha waa mid aad loo jecel yahay iyo waxa loo isticmaalaa in warshado badan - qurxiyo, saxarka iyo warqad, kiimikada, dhar, cunto. Waxa loo isticmaalaa sida daro ah E-524, waayo goobta degassing iyo diyaarinta biodiesel.

Sayidka, sodium hydroxide, - badisid ah, kaas oo la wada isticmaalo ee beeraha kala duwan ee hawlaha aadanaha ay sabab u tahay dabeecadda kiimikaad Waxyeelo.
