Oxides emuncu: Inkcazelo emfutshane yeqela

oxides emuncu - iqela kunokuba elikhulu kwezinto ezinzima azithethelele alkalis. Xa oku kusenzeka loo ukubunjwa ityuwa. Kodwa isakudityaniswa nee-asidi, abayi basebenzisane.

oxides emuncu izenze nonmetals. Umzekelo, eli qela inokuquka isalfure, iphosphate kunye chlorine. Ngaphezu koko, izinto ngempahla efanayo ukuze kwakheke ekuthiwa-elements sethutyana ukuba Valence of emihlanu ukuya esixhenxe.

oxides emuncu ukusabela ngamanzi kungenzeka acid. acid nganye ezingaphiliyo ke oxide ahambelanayo. Umzekelo, oxides sulphur zakha sulphate kunye sulphite acid kunye phosphorus - asidi ortho kunye metaphosphate.

oxides emuncu kunye neendlela lokulungiselela lwabo

Kukho iindlela ezininzi esisiseko yokuvelisa oxides kunye iipropati acid.

Eyona ndlela iqhelekileyo igcwala-athom nonmetal mpilo. Ngokomzekelo, xa zakudibana oxygenic phosphorous ifunyenwe phosphorus oxide. Kakade ke, le ndlela akusoloko kusenzeka.

Enye indlela eliqhelekileyo - ekuthiwa-badubula oxygens sulfides. Ngaphezu koko, oxides salungiselela yi indlela neetyuwa ezithile nee-asidi.

Maxa wambi ezisetyenziswa kwiilebhu kunye necebo eyahlukileyo kancinane. Ngexesha abasabela ngayo ehambelana acid amanzi odlayo - inkqubo emzimbeni lwenzeka. Phela, oko ke yaziwa oxides emuncu phantsi elinye igama - anhydrides acid.

Iipropati lwemichiza oxides emuncu

Njengoko sele kukhankanyiwe, le anhydrides ukuba awasabela ngayo kunye oxides ezisisiseko okanye kwealkali. Ngenxa yendlela uvelisa ehambelana ityuwa asidi, njengoko ukusabela kunye nesiseko kwaye namanzi. Le nkqubo ephawula iimpawu ezingundoqo oxides emuncu. Ukongezelela, anhydrides musa azithethelele asidi.

Enye impahla ezi zinto - kukukwazi azithethelele iziseko amphoteric kunye oxides. Ngenxa yenkqubo efana lwakha iityuwa.

Ukongeza, ezinye anhydrides basabela ngamanzi. Ngenxa yale nkqubo, ukuyilwa esiti ohambelana. Oku ukuzithengela elebhu, umzekelo, sulphuric acid.

Eyona anhydrides ziqhelekileyo: inkcazelo emfutshane

Eyona oksayidi ziqhelekileyo kwaye laziwa asidi kuthathwa ukuba icarbon dioxide. Le nto idla yigesi ezingenambala kwaye ayinavumba, kodwa incasa buthathaka ubumuncu.

Phela, phantsi koxinzelelo umoya kwekharbon diokside zibekhona nokuba sukube okanye uhlobo eziqinileyo (ice eyomileyo). Ukuze ukuguqula le carbon dioxide ibe lulwelo, kuyimfuneko ukuba ukwandisa uxinzelelo. Le propati isetyenziselwa ukugcinwa kwezinto.

Carbon dioxide liqela greenhouse, ngokuba umhlaba lobuso ethintela reyi infrared ubambe ubushushu apha emoyeni. Kodwa, le nto ibalulekile kakhulu eziphilayo. Icarbon dioxide equlethwe umoya umhlaba wethu. Ukongeza, oku kusetyenziswa izityalo photosynthesis.

Isalfure trioxide, okanye sulphur trioxide - omnye ummeli eli qela yezinto. Phantsi kweemeko eziqhelekileyo, loo nto enemibala ulwelo, simbi kakhulu akumnandi, ingakwazi ivumba. Le oxide kubaluleke kakhulu kushishino kwemichiza ke, ngenxa yokuba uninzi kuyo ukuvelisa sulphuric acid.

Silica - kuyenye into eyaziwayo into karhulumente yesiqhelo i njengekristale. Hi ndlela leyi, intlabathi kanye ngenxa yale xhulumaniso. Silicon oksayidi xa itshiswa unako ziyanyibilika kwaye ziqine. Le propati ezisetyenziswayo xa kwenziwa imveliso yeglasi. Ngapha koko, into kakhulu akuthethi ukuqhuba umbane, ngoko ukusetyenziswa kwayo njenge Heating.
