Examples of Copper Compounds
Here is more information about copper(II) nitrate: Copper(II) nitrate also known as cupric nitrate has the formula Cu(NO3)2. Crystals of Cu(NO3)2 (cupric nitrate), Cu(NO3)2.3H2O (cupric nitrate trihydrate) and Cu(NO3)2.6H2O (cupric nitrate hexahydrate) are respectively blue-green, blue and blue. Cu(NO3)2.6H2O decomposes to Cu(NO3)2.3H2O at 26 °C. Cu(NO3)2.3H2O melts at 114 °C and decomposes at 170 °C where its decomposition is a problem for its complete dehydration. Cu(NO3)2 melts at 255 °C. Cupric nitrate and its hydrates dissolve well in water and ethanol. Reaction of copper or copper(II) oxide with nitric acid followed by crystallization can be used to obtain hydrated cupric nitrate. Copper(II) nitrate has some applications like its use as a coloring reagent for ceramics.
