Waa maxay sodium hydrogen sulfate?

Sodium sulfate - waa cusbada acid of sodium iyo sulfuric acid. Muujinaysaa NaHSO4 sheegashada walaxda. Sodium sulfate waa crystal hufan lahayn ur gaar ah. mass The gaws oo ah walaxda waa loo siman yahay si 120,06 grams halkii bar, iyo cufnaanta - 2,472 garaam halkii centimitir oo saddex jibaaran. Waxaa dhalaalayaa at heerkul ah +186 ° C. Marka kulaylinta maalkii laga dheehan karo laba guurka polymorphic - at heerkul ah +140 ° C iyo +170 ° C.

Sodium sulfate la jawaabay karaa alkali, marayay in dareen in sulfate. Sayidka, by it ficil leh sodium hydroxide sameeyay sulfate sodium iyo biyo. Haddii kululaynta xoog badan oo ah wax la mid ah (ilaa +250 ° C ama ka badan) waxaa loo kala qaybiyey pyrosulfate sodium iyo biyo.

Sida caadiga ah, sulfate sodium uusan fal la walxaha kale, si kastaba ha ahaatee, sintering dhacdaa heerkulka ka weyn +450 ° C, ay noqon karto mid ficil la cusbada iyo oxides.

Qiimaha wax ku ool ah oo ah walaxda waa weyn yahay, waayo, kaasu waxaa loo isticmaalaa in metallurgy cuntrooyinka (sida ka daadanayo), waxa ay sidoo kale u dhaqmo sida reagent ah ee sulfates oxides turjumaad. Waa denaturing xoog leh. Waxaa si balaadhan looga isticmaalo karinta (si rasmi ah u diiwan gashan daro cuntada E514).

Si kastaba ha ahaatee, inkastoo ay muhiim nolosha aadanaha, sodium hydrogen sulfate sidoo kale noqon kartaa khatar, isagoo alkali xoog leh, walax waa mid aad u xoqe, xiriir la maqaarka ka tago kartaa gubasho daran, taasoo keenta waxyeelo badan iyo indhaha. Khatarta ugu weyn waxaa ku dhacaan mareenka caloosha iyo mindhicirka. Waxaa sidoo kale waa shay aad u waxyeello iyo neefsasho ah uumi.

Sababo la xiriira saamaynta taban ee bisulfate sodium on jidhka bini'aadamka waa walax calaamad caalami ah oo ka mid ah "Danger" calaamadeeyay waa orange ah square, dissected laba dadab Garaacood madow. Calaamad A sheegay in ku saabsan khatarta walax keliya ma aha ee aadanaha, laakiin sidoo kale deegaanka, iyo sidoo kale xayiraad ku saaray in ay wax soo saarka.

Waayo, sodium loo baahan yahay si ay u qabtaan hydrogensulfate falcelinta dhexeeya acid xoog sulfuric iyo hydroxide sodium, iyo acid ee sulfuric waa in ka badan. Sidaas darteed, reaction this saarta bisulfate sodium iyo biyo.

Si kastaba ha ahaatee, ka hor inta aadan qaadan rasiidka ee wax this in uu iska heli sodium. Diyaarinta sodium waxaa sidoo kale aan adag nidaamka, iyo qaar ka mid ah hababka waa u suurtoobaan xitaa in guriga.

Mid ka mid ah hababka ugu horreeya waa falcelinta of sodium hesho dib u soo kabashada ee carbonate sodium (Na2CO3) ee dhuxusha heerkulka sare ah (ku dhowaad +1000 ° C). Its natiijada ahayd in la helo sodium saafi ah oo go'doon ah carbon monoxide. Samaynta dareen ma ahaa mid aad u waqti, laakiin ay sabab u tahay in la sii daayo carbon monoxide, waxa ay noqotay mid aad u khatar ah.

Sidaa darteed waxaa la Been abuurtay hab kale ee diyaarinta - electrolysis ee la shubay chloride sodium. Faa'iidada ee habkan waa ay ammaanka qaraabo ma aha oo kaliya, laakiin sidoo kale ka yar ee heerkulka hoos u kululaynta walaxda: +600 ° C halkii +1000 ° C. Taasi waa, habkan waxaa loo isticmaali karaa guriga - haddii, dabcan, waxaa suurogal ah ee kululaynta of chloride sodium (cusbo badan) ku yidhi heerkulka.

On ku salaysan sodium - ee element kiimikaad-firfircoon ee miiska wareegsan - diyaar hydrogensulfate congeners sodium iyo aan ka yarayn muhiim u ah aadanaha. hydrosulfide sodium, cusbo acid iyo hydrogen sodium tayadda - walax Tan. Waxay ka dhigan tahay kiristaalo cad, muujinaysaa by NaHS formula. Waxaa la helay ag marayo sulphide hydrogen iyada oo xal of tayadda sodium iyo tayadda hydrogen by marayay xal sodium hydroxide.

hydrosulfide Sodium sameynayso la alkalis iyo acids, si fudud oxidized by oxygen. By barafku uu noqonayaa madow. Waxaa si weyn loo isticmaalaa: qayb ka mid ah hab loo isticmaalo si loo soo saaro layers maqaarka xad-dhaaf ah, qaybiyay dharka, loo isticmaalo sida wax cayriin ee wax soo saarka ee butifos formaldehyde badan.
