Decomposition of cu oh 2
WebJul 28, 2003 · In authors’ [9] opinion, the solid product of decomposition in this process is Cu 2 (OH) 3 NO 3. Probably, as applied decomposition rate was rather high (60 K min −1), the stages of Cu 2 (OH) 3 NO 3 and CuO x (NO 3) y decomposition were coincided. WebNov 1, 2003 · Copper hydroxide Cu(OH) 2 is metastable. It easily transforms into copper oxide CuO more stable, either in the solid state by a thermal dehydration or at room temperature, in aqueous basic solutions. In the solid state, the transformation is performed at a relatively low temperature, 423 K. It is a topotactic or a pseudomorphic …
