Sa thepa eohle le reagents joale ka mahala mabenkele. E 'ngoe ea lintho tsena ke ho le thata sulfuric acid e. Re nahana ka sehloohong sena, seo ho akarelletsa le moo ho ka rekoa metseng Serussia.

asiti Sulfuric - le ... Transport, polokelo

Ipotsa moo o ka reka acid e sulfuric, hopola pele ka thepa ena e kotsi ho batho. asiti Sulfuric ke mofuta oa sa acid e matla dibasic, moralo lona - H ₂ SO _4. Russia, motsoako ona trioxide sebabole le metsi e hlahisitseng ho latela GOST 667-73, 2184-77, 4240-77. Proizvodnje tsa mokelikeli boima mafura leng ha a na 'mala ofe kapa ofe kapa monko, ho akarelletsa mefuta e sa tsoaneng' maloa, e leng se li fapana ka ho hloka sekoli bona le tsa mahloriso.

asiti Sulfuric o na le tsena tse latelang thepa ea bohlokoa:

• Itseng matla a khoheli - 1,85 g, / cm, ³ (ka se setle sa acid e ka ho feletseng sulfuric - 1,92 g, / cm, ^3, empa ntho ena e na le bohlokoa drawback - hoamisoa ka likhato -10 centigrade).
• A phehile ntlha - +296,5 ^° centigrade, ho crystallization ntlha - + 10,45 ° Celsius.
• Ka concentrations ho fihlela ho 70% nakong futhumatsang le belisoe ea acid e ena ba fuwa feela metsi mouoane. Ha litaba tse ka hare e phahameng ea H ₂ SO ₄ moeeng 'me hape ba oela kotsi acid e excretion.
• Ho phatloha le chang ntho. Holim 'a kopana le metsi a lokelang ho tšajoa itsoara joang ka mabifi, ho fellang ka likhase ba bile teng ba, mouoane, mocheso. Ke ka lebaka leo ha ho sebetsa le asiti sulfuric ke ho hlokahala hore ho be le liaparo tse khethehileng, lieta, sete ya motho lik'hemik'hale tšireletso.

Fetisetsoa matsohong a qetellong mosebedisi sulfuric acid e bobeli tseleng le ho tsamaisa seporo. Ho tsamaea ho sebedisa lik'hontheinara khethehileng acid e sulfuric (bakeng sa acid e botekgeniki sulfuric) kapa acid e manganga tanka (bakeng sa ntafaditsweng H ₂ SO _4).

Nakong ea polokelo e Ke habohlokoa ho hopola hore acid e le sulfuric - ntho nang le chefo e ho ba setho sa sehlopha sa bobeli a le kotsing. The lebetsoeng le sireletsehileng ea mahloriso ea mouoane H ₂ SO ₄ - 1 mg, / limithara ^3. Pele u etsa qeto ea moo ho reka acid e sulfuric (botekgeniki), o lokela ho reka lik'hontheinara khethehileng bakeng sa polokelo. Ka libaka tsa tlhahiso ea lona ka ho eketsehileng obkladyvayut acid e manganga setene.

Ke mang ea entseng e fumana joalo pele tsebe moo ho reka acid e sulfuric, u fa keletso batho.

Tips bakeng sa ho reka

Ho joalo, ke habohlokoa ho hopola lintlha tse latelang:

1. Motho poraefete, maemong a sa tloaelehang, ba rekisa e khōlō palo ya ntho ena - lokela ho butle-butle se fumanang, ho tloha bafepedi tse sa tšoaneng.
2. Tabeng ea ho hlōleha ha fumana ka boela leka ho mouoane H ₂ SO ₄ of electrolyte. The segokanyipalo sa palo e kahodimodimo ka tsela eo a ke ke a feta 1.4 g, / cm, ^3. E le mouoane o etsoang tsoa ka porcelain sejana se se ka lehlabathe hlapa kapa gypsum. Leha ho le joalo ho ke ke ha khoneha ho etsa tshebetso ena ka matlung.
3. Hopola hore re ka rekisa acid e sulfuric ke tlas'a taolo, e le ntho ena e sebelisoa ho hlahisa lithethefatsi, hammoho le liqhomane lapeng-li entseng. Esita le haeba u fumana ho bakeng sa liteko tse se nang molato kapa ho refilling avtoakkumulyatora lintho tse ngata tseo e seng tsa e nyenyane, e ka etsa hore libata masene sa hlokahaleng.
