Sodium hydroxide, ya na ahụ na chemical Njirimara:

Sodium hydroxide, ma ọ bụ caustic soda - inorganic compound nke bụ nke a na klas nke bases ma ọ bụ hydroxides. Na-na na Usoro na ná mba ọzọ a umi na-akpọ caustic soda. Common aha - caustic soda - ọ bụ ruru ya ike corrosive edinam.

Nke a siri ike na-acha ọcha crystalline umi-enwe hygroscopicity,-agbaze na 328 degrees. Sodium hydroxide bụ ngwa ngwa soluble n'ime mmiri na-a siri ike electrolyte. Mgbe dissociation etịbede elu n'ime a metal cation na hydroxide ion.

N'elu mgbasa na mmiri Nleta ifịk compound - alkali - soapy obi na-adị. Mmeghari a wee nnọọ ngwa ngwa - na ịgba na okpomọkụ. Ọ kụrụ caustic ka akpụkpọ mucous membranes na-akpata oké chemical Burns, n'ihi ya, mgbe ị na-arụ ọrụ, ị ga-akpachara anya na-echebe aka gị na anya. Mgbe na kọntaktị na umi na epithelium ma ọ bụ na anya, ọnụ, ọ dị mkpa ka anya dị ka ndị metụtara ebe nwere ike na-asa na mmiri na a na-adịghị ike ngwọta nke acetic (2%) ma ọ bụ boron (3%) nke acid, na mgbe ahụ, ọzọ na mmiri. Mgbe enye mberede aka ahụ tara kwesịrị ịhụ dọkịta.

Sodium hydroxide (chemical usoro nke compound - NaOH, struturnaya - NaOH) - a na ya nọ n'ọrụ umi, nke nwere ike na-eme na ma inorganic na site organic bekee. Ịchọpụta ya na okenye agbanwe agbanwe ga- qualitative mmeghachi omume ka hydroxide ion na a dịgasị iche iche nke na-egosi. N'ihi ya, litmus egosi aghọ ọchịchịrị-acha anụnụ anụnụ, methyl oroma - odo, na phenolphthalein - utu, nke osisi ike nke na-agba ga-adabere na ịta nke alkali.

sodium Gidrksid abanye dị otú ahụ mmeghachi omume:

1. neutralization na asịd, acid oxides na amphoteric ogige. The N'ihi nke a mmeghachi omume bụ guzobe mmiri na nnu gidroksokompleka ma ọ bụ - na ikpe nke na mmeghachi omume na-ndọkwasi nile na amphoteric oxides;

2. mgbanwe na salts;

3. na ọla nke na-ke n'usoro ka hydrogen Beketova elektorhimichesky na nwere a ala nwere;

4. a ndị na-abụghị ọla na halogens;

4. hydrolysis esters;

5. saponification na abụba (kpụrụ ncha na glycerin);

6. mmeghachi omume na alcohols (alkoxides emepụta umi).

Ọzọkwa na wụrụ awụ ụdị caustic soda nwere ike ime poselin na iko, na ọnụnọ nke oxygen - ezi metal (platinum).

Sodium hydroxide nwere ike na-akwadebe site ụzọ:

1. electrolysis nke okenye NaCl (diaphragm na akpụkpọ ahụ usoro)
2. chemical (lime na ferrite usoro).

Na-adịbeghị anya, ndị akacha eji ụzọ na-dabere na electrolysis, n'ihi na ha ọzọ uru.

Caustic soda bụ nnọọ ewu ewu na-eji na ọtụtụ ụlọ ọrụ na - ịchọ mma, pulp na akwụkwọ, chemical, akwa, nri. Ọ na-eji dị ka ihe mmako E-524, n'ihi na degassing ogige na na nkwadebe biodiesel.

N'ihi ya, sodium hydroxide, - a ncha, nke e n'ọtụtụ ebe dị iche iche na n'ubi mmadụ na-eme ruru ya na ya reactive okike.
