Cupric nitrate Cu(NO3)2 - PubChem
WebKsp = 2.2 × 10–20 for Cu(OH)2, Ksp = 1.3 × 10–15 for Co(OH)2. Hi how are you doing today hope you are doing great and safe . Answer is the pic below . Hope this helps good luck … Web寻找本题的突破口应从实验现象进行推理，即依据题意可知铁和AgNO3溶液可以发生置换反应产生Ag，铁也可以与Cu(NO3)2溶液发生置换反应产生Cu，过滤后加入盐酸有白色沉淀生成，说明滤液中还含有AgNO3溶液，当有AgNO3溶液时反应生成的Cu也可以与之反应生成Ag，故本题的关键在于推断出滤液中还含有AgNO3 ... WebConcentrated nitric acid reacts with copper and produce copper nitrate ( Cu(NO 3) 2), nitrogen dioxide (NO 2) gas and water as products. In this reaction, copper is oxidized to its +2 oxidation state while nitric acid is reduced to nitrogen dioxide. After the reaction, color of the solution which contains Cu(NO 3) 2 is blue. it is a cold winter day
