Cov duab ntawm cov tooj liab carbonate (CAS: 12069-69-1): peacock ntsuab zoo amorphous hmoov.tooj liab carbonate hydroxide yog insoluble hauv dej thiab cawv.Nws yog soluble hauv acid, ammonia thiab potassium cyanide daws.
Basic tooj liab carbonate yog ruaj khov ntawm chav tsev kub thiab siab.Basic tooj liab carbonate yog insoluble nyob rau hauv dej txias thiab cawv, decomposed nyob rau hauv dej kub, yaj nyob rau hauv acid los ua tooj liab ntsev.Soluble nyob rau hauv cyanide, ammonia, ammonium ntsev thiab alkali hlau carbonate aqueous tov, tsim tooj liab complex.Brown tooj liab oxide yog tsim thaum boiled nyob rau hauv ib tug tov ntawm alkali carbonate.Tsis ruaj tsis khov rau hydrogen sulfide.Thaum tshav kub kub rau 200 ℃ kom decompose dub tooj liab oxide, dej (me me me ntawm condensation tsim thaum txias) thiab carbon dioxide.Tsis ruaj tsis khov hauv hydrogen sulfide gas.Solubility hauv dej yog 0.0008%.Copper carbonate yog plua plav, yog li tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag thiab nqus pa.
Insoluble hauv dej, soluble hauv ammonia los tsim tooj liab ammonia txuam ions.Decompose thaum rhuab mus rau 220 ℃.Lub 2∶1 pib tooj liab carbonate yog lub ntuj-xiav hmoov siv lead ua.Yog tias muab tso rau hauv huab cua ntev, nws yuav nqus dej noo thiab tso tawm ib feem ntawm cov pa roj carbon dioxide, maj mam dhau los ua 1∶1 yam yooj yim tooj liab carbonate, insoluble hauv dej, tab sis soluble hauv ammonia thiab tsim cov tooj liab ammonia ion.
