Sulfur dioxide. Formula, helitaanka, guryaha kiimikada

baaruud Oxide (baaruud dioxide, baaruud dioxide, baaruud dioxide) - waa gaas Biyuhu isagoo urta sida caadiga ah af badan sifo (ur la mid ah kulan ah ciinwaanka). Liquefied cadaadis at heerkulka qolka. Sulfur dioxide waa L. biyo, sidaas darteedna la xirrira deganayn sulfuric acid. Sidoo kale, walax tani waxaa la kala diri in acid sulfuric iyo ethanol. Tani waa mid ka mid ah qaybaha ugu muhiimsan ee halabuurka ah ee gaaska Kobenhagen.

Sida diyaariyey baaruud dioxide

Diyaarinta SO2 - baaruud dioxide - habka warshadaha ka kooban yahay in baaruud ama galidda ee sulfides gubanaya (pyrite waxaa inta badan loo isticmaalaa).

4FeS2 (pyrite) + 11O2 = 2Fe2O3 (xabagta birta) + 8SO2 (baaruud dioxide).

In xaaladaha shaybaarka, dioxide baaruudda laga heli karaa by tallaabada ee hydrosulfites acids xoog iyo sulfites. Sayidka keentay acid sulfurous si degdeg ah decomposes biyaha iyo baaruud dioxide. Tusaale ahaan:

Na2SO3 (sodium sulfite) + H2SO4 (sulfuric acid) = Na2SO4 (sodium sulphate) + H2SO3 (sulfurous acid).
H2SO3 (sulfurous acid) = H2O (oo biyo ah) + SO2 (baaruud dioxide).

Habka saddexaad ee soo saara baaruud dioxide la kulmin xoog sulfuric acid by kulaylinta on a Biraha firfircoon ka yar. Tusaale ahaan: CU (copper) + 2H2SO4 (sulfuric acid) = CuSO4 (copper sulfate) + SO2 (baaruud dioxide) + 2H2O (oo biyo ah).

guryaha Chemical baaruud dioxide

formula ee baaruud dioxide - SO3. Qalabkan waxaa la xiriiraa oxides acidic.

1. dioxide baaruud ayaa u kala diray biyo, oon la xirrira sulphurous acid. Under xaaladaha caadiga ah, dareen-celinta ay tani tahay karo.

SO2 (baaruud dioxide) + H2O (oo biyo ah) = H2SO3 (sulfurous acid).

2. alkalis baaruud dioxide la xirrira sulfite. Tusaale ahaan: 2NaOH (hydroxide Sodium) + SO2 (baaruud dioxide) = Na2SO3 (sodium sulfite) + H2O (oo biyo ah).

3. hawl gaaska baaruud Chemical waa ku filan sare. The guryaha hoos ugu dhawaaqaa baaruud dioxide. In reactions sida heerka uu qayilo baaruud kordhay. Tusaale ahaan: 1) SO2 (baaruud dioxide) + Br2 (bromine) + 2H2O (oo biyo ah) = H2SO4 (sulfuric acid) + 2HBr (bromide hydrogen); 2) 2SO2 (baaruud dioxide) + O2 (oxygen) = 2SO3 (sulfite); 3) 5SO2 (baaruud dioxide) + 2KMnO4 (-KP) + 2H2O (oo biyo ah) = 2H2SO4 (sulfuric acid) + 2MnSO4 (sulphate manganese) + K2SO4 (potassium sulfate).

jawaab Last - tusaale ka mid ah jawaabta oo tayo sare leh si ay u SO2 iyo SO3. midab guduud dhacdaa xal).

4. In la eego joogitaanka yaraynta xoog baaruud dioxide muujiyaan karaa sifooyinka oksidheeyeyaal ah. Tusaale ahaan, si loo soo saaro in baaruud warshadaha qodniinka- ka gaasas qiiqa, iyadoo la isticmaalayo dib-baaruud dioxide la carbon monoxide (CO): SO2 (baaruud dioxide) + 2CO (carbon monoxide) = 2CO2 (carbon dioxide) + S (baaruud).

Sidoo kale guryaha oxidative walax this waxaa loo isticmaalaa si aad u hesho ksiloty fosfornovaristoy: PH3 (phosphine) + SO2 (baaruud dioxide) = H3PO2 (acid fosfornovaristaya) + S (baaruud).

Halkee baaruud isticmaalo dioxide

Guud ahaan dioxide baaruudda loo isticmaalo in la soo saaro sulfuric acid. Sidoo kale waxaa loo isticmaalaa sida a preservative (E-220) ee soo saaridda ee cabitaannada fudud (khamri iyo cabitaanada kale ee celcelis ahaan category qiimaha). Sababo la xiriira hantida gaas si ay u dilaan kala duwan ee sheyga, waxay fumigated bakhaaro, iyo dukaanka cuntada. Intaa waxaa dheer, baaruud dioxide waxaa loo isticmaalaa bleaching dhogor idaad, xariir, caws engegan oo kale (kuwa qalabka oo aan la bleached kara chlorine). In ka laboratories baaruud dioxide waxaa loo isticmaalaa sida dareeraha ah iyo si aad u hesho cusbada kala duwan ee sulfurous acid.

saamaynta nafsaaniga ah

Sulfur dioxide wuxuu leeyahay sifooyin sun ah oo xoog leh. Calaamadaha ku-sumowga - qufac, sanka oo dareera, xabeeb, dhadhanka hanti ah oo afka, xanxantayn xooggan ee cunaha. Neefsasho baaruud dioxide at uruuray sare u kacaya liqidda oo dhib ah iyo margashadu, disorder hadalka, lallabo iyo matag laga yaabaa in barar sambabada ba'an.

MPC baaruud dioxide:
- gudaha - 10 mg / m³;
- celcelis ahaan hawada shaqo-in ugu badnaan - 0.05 mg / m³.

Dareenka si dioxide baaruud in aadanuhu shaqsi, dhirta iyo xoolaha way kala duwan yihiin. Tusaale ahaan, ka mid ah geedaha bjørk ugu adkaysi u ah iyo geed alloon ah, oo ugu yaraan - iyo gran.
