Copper hydroxide yog dab tsi?Dab tsi yog qhov txawv ntawm tooj liab hydroxide thiab tooj liab carbonate?Verdigris yog dab tsi?
Copper (II) hydroxide yog hydroxide ntawm tooj liab, tshuaj formula Cu (OH) 2.Copper hydroxide yog lub teeb ntsuab xiav lossis xiav-ntsuab khoom.Qee hom tooj liab (II) hydroxide raug muag raws li "ruaj khov" tooj liab (II) hydroxide, txawm hais tias lawv yuav muaj cov sib xyaw ntawm tooj liab (II) carbonate thiab hydroxide.Tooj hydroxide yog lub hauv paus muaj zog, tab sis nws cov solubility hauv dej yog tsawg heev uas nws nyuaj rau saib ncaj qha.
Copper hydroxide (II) tau paub rau tib neeg txij li thaum tooj liab smelting pib nyob ib ncig ntawm 5000 BC, txawm hais tias alchemists yog thawj zaug ua nws.Qhov no yog yooj yim ua los ntawm kev sib tov lye nrog ib tug daws ntawm xiav sulfuric acid, ob qho tib si tshuaj paub los ntawm ancient sij hawm.
Nws tau tsim nyob rau hauv kev lag luam nplai nyob rau hauv lub xyoo pua 17th thiab 18th los tsim cov xim xws li xiav verdant thiab plum ntsuab.Cov pigments no yog siv hauv ceramics thiab painting.
