Sodium hydroxide, ta jiki da kuma sinadaran Properties:

Sodium hydroxide, ko caustic soda - inorganic fili abin da nasa ne a aji na sansanonin ko hydroxides. Har ila yau a cikin dabara da kuma kasashen waje da wannan abu ya kira caustic soda. Common sunan - caustic soda - shi ne saboda ta karfi lalatattu mataki.

Wannan m fari crystalline abu da ciwon hygroscopicity, dab a 328 digiri. Sodium hydroxide ne readily mai narkewa a cikin ruwa da kuma shi ne mai karfi electrolyte. Lokacin da dissociation karya up cikin wani karfe cation da hydroxide ions.

Bayan rushe a ruwa Forms da aiki fili - Alkali - soapy Feel. Wannan dauki fitowa sosai hanzari - tare da fesa da kuma zafi. Yana buga caustic to fata da kuma mucous membranes sa mai tsanani sinadaran konewa, don haka a lokacin da ka yi aiki, dole ne ka yi hankali da kare hannuwanku da idanu. Bayan lamba tare da abu zuwa ga epithelium ko da idanu, baki, shi wajibi ne da zaran ta shafi yankunan iya wanke da ruwa, kuma wani rauni bayani na acetic (2%) ko boron (3%) na acid, sa'an nan kuma da ruwa. Bayan samar da gaggawa agaji ga wadanda ke fama bukatar ganin likita.

Sodium hydroxide (sinadaran da dabara na fili - NaOH, struturnaya - NaOH) - a chemically aiki abu, wanda zai iya amsa tare da biyu inorganic kuma daga kwayoyin abubuwa. Gane shi a cikin ruwa-ruwa mafita zai ingantaccen dauki ga hydroxide ion da dama Manuniya. Saboda haka, litmus nuna alama zama duhu blue, methyl orange - rawaya, da kuma phenolphthalein - rasberi, cikinsa da tsanani da launi zai dogara ne a kan taro na Alkali.

sodium Gidrksid shiga cikin irin wannan dauki:

1. neutralization da acid, acid oxides da amphoteric mahadi. A sakamakon wannan dauki da samuwar ruwa da gishiri gidroksokompleka ko - a cikin hali na dauki tare da kwasfansu, da amphoteric oxides.

2. musayar tare da salts.

3. tare da karafa da su ne a jere don hydrogen Beketova elektorhimichesky kuma suna da wani low m.

4. wani maras karafa da kuma halogens.

4. hydrolysis esters.

5. saponification da fats (kafa da sabulu da kuma glycerin).

6. dauki tare da alcohols (alkoxides samar abu).

Har ila yau, a zubi form caustic soda iya halaka ain da kuma gilashin, da kuma gaban oxygen - da daraja karfe (platinum).

Sodium hydroxide iya shirya ta hanyoyin:

1. electrolysis na ruwa-ruwa NaCl (diaphragm da kuma membrane Hanyar)
2. sinadaran (lemun tsami da kuma ferrite Hanyar).

A cikin 'yan shekaru, da aka fi amfani da hanyoyin da su ne bisa electrolysis, saboda suna da riba.

Caustic soda ne Popular kuma an yi amfani da mutane da yawa masana'antu - kwaskwarima, ɓangaren litattafan almara da kuma takarda, sunadarai, yadi, abinci. Ana amfani da a matsayin ƙari E-524, don degassing gabatarwa da kuma a cikin shirye-shiryen da biodiesel.

Saboda haka, sodium hydroxide, - wani lye, wanda aka yi amfani da ko'ina a fannoni daban daban na ayyukan mutane saboda ta chemically amsawa yanayi.
