ʻO ke kumu kemika Phe o ka oxide kālā ʻo Ag2O, me ke kaumaha molekala o 231.74. ʻeleʻele ʻeleʻele ʻeleʻele a hinahina paha, me ka mānoanoa o 7.143g/cm, hiki ke hoʻoheheʻe ʻia a lilo i kālā a me ka oxygen ma 300 ℃. Hiki ke hoʻoheheʻe ʻia i loko o ka wai, hiki ke hoʻoheheʻe ʻia i loko o ka waikawa nitric, ammonia, sodium thiosulfate, a me nā solutions potassium cyanide. Ke hoʻohana ʻia ka hopena ammonia, pono e mālama ʻia i ka manawa kūpono. Hiki i ka ʻike lōʻihi ke hoʻokahe i nā kristal ʻeleʻele pahū loa - nitride kālā a i ʻole sulfite kālā. Hoʻohana ʻia ma ke ʻano he oxidant a me ke aniani kala. Hoʻomākaukau ʻia e ka hoʻoheheʻe ʻana i ka wai nitrate kālā me ka solution sodium hydroxide.

ʻEleʻele cubic crystalline a i ʻole ka pauka ʻeleʻele ʻeleʻele. Ka lōʻihi o ka pilina (Ag O) 205pm. Decomposition ma 250 degrees, hoʻokuʻu i ka oxygen. 7.220g/cm3 (25 degere). Decompose mālie ke kukui. E hoʻopili me ka ʻakika sulfuric e hana i ka sulfate kālā. Hiki ke hoʻoheheʻe ʻia i ka wai. Hiki ke hoʻoheheʻe ʻia i loko o ka wai amonia, ka hopena sodium hydroxide, dilute nitric acid, a me ka solution sodium thiosulfate. ʻAʻole hiki ke hoʻoheheʻe ʻia i ka ethanol. Hoʻomākaukau ʻia ma ka hana ʻana i ka wai nitrate kālā me ka solution sodium hydroxide. Hoʻohana ʻia ʻo Wet Ag2O ma ke ʻano he catalyst ke hoʻololi i nā halogens me nā pūʻulu hydroxyl i ka synthesis organik. Hoʻohana pū ʻia ma ke ʻano he mea mālama a me nā mea uila.

 

Waiwai kemika

E hoʻohui i kahi ʻoluʻolu hoʻoheheʻe i ka solution nitrate kālā e loaʻa ai. ʻO ka mea mua, loaʻa ka hopena o ka hydroxide kālā a me ka nitrate, a hoʻoheheʻe ʻia ka hydroxide kālā i loko o ka wai ʻona a me ka wai ma ka lumi wela. Hoʻomaka ka oxide kālā e hoʻoheheʻe i ka wā i wela ai i 250 ℃, e hoʻokuʻu ana i ka oxygen, a me ka decompose wikiwiki ma luna o 300 ℃. Hiki ke hoʻoheheʻe ʻia i loko o ka wai, akā hiki ke hoʻoheheʻe ʻia i nā hopena e like me ka nitric acid, ammonia, potassium cyanide, a me ka sodium thiosulfate. Ma hope o ka ʻike lōʻihi ʻana i kāna solution ammonia, hiki i nā kelika ʻeleʻele pahū ikaika i kekahi manawa ke hoʻoheheʻe - hiki paha i ka nitride kālā a iminide kālā paha. I loko o ka organik synthesis, hoʻohana pinepine ʻia nā pūʻulu hydroxyl e hoʻololi i nā halogens a i ʻole he oxidants. Hiki ke hoʻohana ʻia ma ke ʻano he kala i ka ʻoihana aniani.

 

Kaʻina hoʻomākaukau

Hiki ke loaʻa ka ʻokikene kālā ma ka hoʻopili ʻana i ka alkali metala hydroxide me ka nitrate kālā. [1] Hoʻopuka mua ka pane ʻana i ke kālā hydroxide paʻa ʻole, e hoʻoheheʻe koke ʻia no ka loaʻa ʻana o ka wai a me ke kālā oxide. Ma hope o ka holoi ʻana i ka wai, pono e hoʻomaloʻo ʻia ma lalo o 85 ° C, akā paʻakikī loa ka hoʻohemo ʻana i kahi wai liʻiliʻi mai ka oxide kālā ma ka hopena no ka mea i ka piʻi ʻana o ka mahana, e decompose ke kālā oxide. 2 Ag+ + 2 OH− → 2 AgOH → Ag2O + H2O.

 

Hoʻohana kumu

Hoʻohana nui ʻia ma ke ʻano he catalyst no ka synthesis kemika. Hoʻohana ʻia ʻo ia ma ke ʻano he preservative, mea uila uila, kala aniani, a me ka mea wili. Hoʻohana ʻia no ka lāʻau lapaʻau a ma ke ʻano he aniani polishing agent, kala, a me ka hoʻomaʻemaʻe wai; Hoʻohana ʻia ma ke ʻano he polishing a me ke kala kala no ke aniani.

 

Laulā noi

ʻO ke kala ʻona ka mea electrode no nā ʻeke ʻeke kālā. ʻO ia hoʻi kahi mea hoʻonāwaliwali nāwaliwali a nāwaliwali i ka synthesis organik, hiki ke hana me nā paʻakai imidazole 1,3-disubstituted a me nā paʻakai benzimidazole e hana i nā azenes. Hiki iā ia ke hoʻololi i nā ligands paʻa ʻole e like me cyclooctadiene a i ʻole acetonitrile ma ke ʻano he carbene transfer reagents e synthesize transition metal carbene complexes. Eia kekahi, hiki ke hoʻololi i nā bromides a me nā chlorides i loko o ka waiʻona i nā haʻahaʻa haʻahaʻa a ma ke alo o ka mahu wai. Hoʻohana pū ʻia me ka iodomethane ma ke ʻano he methylation reagent no ka nānā ʻana i ka methylation kōpaʻa a me nā hopena elimination Hoffman, a me ka oxidation o nā aldehydes i nā waikawa carboxylic.
