Keleawe'okesaside

Cuprum (cu) pili i ka helu o AEeOEXAaI ke hooheheeia. Ua Ua wehewehe aku ma ke kahua o Nine Inch i huiʻia me ka'okesaside Hawaii o +1 a me +2. No ka laʻana, na oxides elua, o ka hui o nā oihana mua o cu a me ka oxygen O:'okesaside moku'āina +1 - cuprous'okesaside Cu2O a me ka'okesaside moku'āina +2 - keleawe'okesaside CuO. I loko nō o ka mea e komo ana i ka ia Nine Inch hehee lakou, akā, kela mea keia mea o lakou i kona mau kūikawā ano. Ma ke anu metala reacted loa weakly me ka o oxygen i loko o ka lewa, uhi me ka ho film, i mea he keleawe'okesaside, a ua ālai ''okesaside pono cuprum. I ka enaena, he mea waiwai me ke kaʻina, helu 29 ma ka papa'āweʻaweʻa kemika papaʻaina ua pau oxidized. Ma keia hihia kekahi i hanaʻia o ka keleawe'okesaside (II): 2Cu + O2 → 2CuO.

Nitrous'okesaside mea he brownish-ulaula paa me ka hakakino kaumaha o 143,1 g. / Kameleona. Ka hui i ka mahele heheʻe i ka mahana o ka 1235 ° C, he baila aʻela i wahi o 1800 ° C. Ia, aole ia e hoike mai i loko o ka wai, akā, hoike mai i loko o nāʻakika. Ulu keleawe'okesaside (I) ma ka ammonia pāʻoihana (i kia), ho okumu i kekahi colorless luna '[cu (NH3) 2] +, a ua hikiwawe oxidized ma ka lewa i ka ammonia luna' uliuli-poni waihoʻoluʻu [cu (NH3) 4 (H2O) 2] 2+ mea hoʻoheheʻeʻia i loko o hydrochloricʻakika e lilo CuCl2. I mea uholo uila ke kālaikūlohea mōʻaukala Cu2O o kekahi o ka loa? Anoee pono hana.

Keleawe'okesaside (I), iʻikeʻia me nitrous i walaʻauʻana waiwai. Ua hiki ke hoomakaukau e'okesaside o ka metala: 4Cu + O2 → 2 Cu2O. Impurities e like me ka wai a me kaʻakika e pili i ka uku o keia kaʻina, a me ka hou'okesaside i ferrous'okesaside. Cuprous'okesaside hiki e ia ka pono i loko o sulfuricʻakika, ma ia ho okumu i ka mea hiki ke hooheheeia maemae, a me ka paakai o ia mea: H2SO4 + Cu2O → cu + CuSO4 + H2O. A like noaia mea he AaOIeIOUIeXAOAaIN o ka'okesaside me keʻano o ka'okesaside o kekahi metala a me nā oxygen ma-i loaʻa nāʻakika. Ma ka naoh o nitrousʻakika me ka halogenated monovalent metala paakai palapala: 2HCl + Cu2O → 2CuCl + H2O.

Loaʻa keleawe'okesaside (I) ma ke ano maoli, heʻulaʻula e eliia (keia inoa kahiko, a me na mea like saredio cu), mea pōhaku i kapaia "Cuprite". Ma kona ho okumu i ka lōʻihi manawa. Ua hiki ke hua mai la artificially paha ma kiʻekiʻe mahana ma lalo kiʻekiʻe ka oxygen puʻe. Nitrous ana hoʻohana like me ka fungicide, me he pigment, e like me ka papa anuʻu loa kai antifouling agena ma ke HW a me ka moana, a no hoi paha me ka hōʻeleu.

Naʻe, i ka hope o keia waiwai me ka Nine Inch haʻilula Cu2O ma luna o ka meaola i e nā palapala. I ka ana, ka mea e hookomo ana pokole o ka hanu, cough, a me ka ulceration a me perforation o ka naehana'āpana. Inā ale, o keʻano ukiuki i ka gastrointestinal'āpana, pu ma ka luaʻi, ka eha, a me ka diarrhea.

Higher'okesaside keleawe ma ka helehelena o ka lepo mai ka mea eleele iʻeleʻele. Ua lŘlŘ maoli ai e like me ka mea pōhaku, "ke ano" i loko o konaʻoe i palapala. Kona mahele heheʻe i ka mehana o 1326 ° C, nā kapuahi wahi 2,000 ° C. He insoluble i loko o ka wai, ka waiʻona, 'amoniuma hydroxide, 'amoniuma kalepona pāʻoihana. Wailana ma koʻana koko pāʻoihana o'amoniuma koloriside a me ka potasiuma cyanide. Uaʻeleʻele paa hiki ke loaa ma ka paio hahana maoli nō ma ka lewa cu. Naʻe, i loko o keia hihia kekahi i hana'okesaside cu. Makaukau o ke keleawe'okesaside CuO kohoʻia me ka hahana maoli nō kēia i huiʻia:

• keleawe (II) nitrate 2Cu (NO3) 2 4 → NO2 + O2 + 2CuO;

• keleawe (II) hydroxide cu (OH) 2 → H2O + CuO;

• keleawe (II) kalepona CuCO3 → CO2 + CuO.

Cuprum (II)'okesaside ka walaʻauʻana, pela no ka mea, hoike mai ka mea pōhaku nāʻakika (hydrochloric, sulfuric a me ka nitric), e haawi aku i ka like divalent cu paʻakai:

• 2HCl + CuO → CuCl2 + H2O;

• H2SO4 + CuO → CuSO4 + H2O;

• 2HNO3 + CuO → cu (NO3) 2 + H2O.

Reacts keleawe'okesaside (II) me ka i kia mekala 'åkilikai e hana i ka paʻakai: 2 KOH + CuO + H2O → K2 [cu (OH) 4].

e hoemi i ka'okesaside ke i ka mea hao cu ma naoh me ka hydrogen paha o carbon monoxide :

• H2 + CuO → cu + H2O;

• CO + CuO → cu + CO2.

E ho ohana i ke keleawe'okesaside (II) i loko o ka pālolo (me he pigment) no ka glaze (uliuli, omaomao a me ka ulaula, a me kekahi manawa a pink, oho aole hoi i eleele). Ua i hoʻohana Ua like me ka meaʻai mea hoʻonui i ka holoholona, e ho'ēmi i cuprum deficiency i loko o ke kino. Kēia abrasive mea, i mea e pono ai i ka Polish'ōnohi lako a pan. Ua ua hoʻohana 'ia no ka? Iecaianoaaiiie o maloʻo iuo aaoa? No ka makaukau o kekahi cu paʻakai. Ka hui Ua i hoʻohana 'ia i loko o CuO kuʻihao keleawe oka a pau.

Waiū no ka Nine Inch hui CuO hiki no hoi e weliweli no ke kanaka kino. I ka ana, ma o na la akemāmā ae hookaawale. Keleawe'okesaside (II) ke i kuni mea hao ohu (MFF). Cu'okesaside hoʻonāukiukiʻana mai o ka loli ma ka ili kala like 'ole, ke i pilikia me ka eyesight. Ka wā kino me nitrous hiki aku ai i kaʻapu kōheoheo, i ua pu ma symptoms o ka luaʻi a me ka eha.
