“…4(b). The overall percent weight loss for the CuO (c) precursor synthesized at 2 h is about 33.9% which is close to the theoretical weight loss expected for Cu 2 (OH) 3 NO 3 (33.74%) [53]. Whereas, the precursor synthesized at 6 h precipitation time shows an overall weight loss of only about 12%.…”

“…The syntheses for the three members of the copper(II) hydroxyl nitrate family and the corresponding Powder-XRD, have been reported by Yoder, et al (2010). The first time preparation of gerhardtite might be reported by Cumming and Gemmell (1913) and thermal investigation of gerhardtite has also been reported (Ilcheva et al, 1979), while Aguirre et al (2011) reported simple route for the preparation of copper(II) hydroxyl salt, Cu(NO3)2•3Cu(OH)2, by the reaction of copper(II) nitrate trihydrate with Mg(OH)2. Thus, it is possible that the mixing solution of copper(II) nitrate with hydroxide might contain basic copper(II) nitrate.…”

“…While, Cu(NO3)2•5Cu(OH)2 is known as likasite (Frost et al, 2005) which has also been prepared (together with gerardite and rouaite) by Yoder et al (2010). It was synthesized by slow addition (1 mL/min) of 50 mL of 0.1 M NaOH to a mixture of 30 mL of 0.1 M copper(II) acetate and 10 mL of 0.1 M sodium nitrate with stirring for about 20 h. From the study, it has been reported that gerhardtite is the most stable at room temperature, while the detailed thermal stability of this compound has also been reported (Ilcheva, Maneva & Bozadziev, 1979). However, we surprisingly obtain the formula likasite in our work via titrating NaOH with Cu(NO3)2 procedure in an aqueous solution.…”

The main purposes for this work are to formulate and characterize the infrared (IR) and magnetic moment of the compounds resulted from the slow titration of copper(II) nitrate with sodium hydroxide and in the reverse procedures in an aqueous solution. The titration is carried out with various concentrations and at a constant temperature, ⁓ 19 oC, and monitored using pH meter with the rate of the titration⁓ 1 mL per minute. The corresponding data of change in mole ratio of Cu2+/OH- against pH reveals that the end point of the titration occurs at pH about 8, leading to stoichiometry formula, 3Cu(NO3)2.5Cu(OH)2, but Cu(NO3)2.5Cu(OH)2 in the reverse procedure (OH-/Cu2+). The pale blue for the former but deep blue compounds were isolated and then characterized IR spectroscopy and magnetic moment. Both compounds containing nitrate ion are evident from the corresponding IR spectra, and their magnetic moment values which were found in the range of 1.7-1.9 BM, are to be normal for copper(II) salt corresponding to one unpaired electron in the electronic configuration.

“…Gmelin suggests that the lower values apply to decomposition of moist salt, whereas the higher values apply to the dry state. The most recent studies have been performed by Auffredic et al [25] and by Ilcheva et al [26] . The former observed the beginning of decomposition at about 170°C, using a heating rate of 3°C per hour.…”

Previously reported work by others indicates that dicopper trihydroxide nitrate, Cu2NO3(OH)3, forms on copper and copper alloys subjected to irradiated moist air near room temperature. We have performed experiments over a range of temperature and humidity, and have found that this species is formed at temperatures up to at least 150° C if low to intermediate relative humidities are present. At 150°C and 100% relative humidity, only Cu2O and CuO were observed. The relative general corrosion rates of the copper materials tested in 1-month experiments at dose rates of 0.7 and 2.0 kGy/h were Cu > 70/30 Cu-Ni > Al-bronze. High-nickel alloy 825 showed no observable corrosion.
