Symptoms/Injuries After Skin Contact: Prolonged exposure may cause skin irritation. In this reaction, as copper (II) decomposes to form copper oxide, nitrogen dioxide gas, and oxygen gas as products, therefore, it is a decomposition reaction. So, when you mix a solution of copper nitrate (light blue solution) and sodium hydroxide (clear solution) you will see a light blue precipitate form (Cu(OH)2) and NaNO3 in solution. All of these carbonates are white solids, and the oxides that are produced are also white solids. Hazardous Polymerization Has not been reported. Figure 4 shows that the rate of catalytic decomposition of the copper catalyst with chlorate solution and oxygen is much higher than that of the chlorate solution alone and that passing oxygen with catalyst in the absence of chlorate does not promote decomposition. Catalytic Decomposition of Organic Dye. The decomposition of HAN is catalyzed by metals commonly found in storage tanks, a factor limiting its use. This method is similar to the last step in the Ostwald process.
