Widespread Solid Solutions of Hexahydrated Cobalt and Nickel Nitrates: Solid–Liquid Equilibria at 273.15 and 303.15 K and Characterization of Mixed Crystals of Homogeneous Composition
Abstract:The isothermal solubility curves of the H 2 O−Co(NO 3 ) 2 − Ni(NO 3 ) 2 ternary system were studied at 273.15 and 303.15 K, using a synthetic method based on conductivity measurements. The analysis of the equilibrium phases' composition was conducted by UV−visible spectroscopy. The solid phases were first characterized by powder X-ray diffraction, which showed the formation of two substitutional solid solutions:which has a triclinic structure. Then the evolution of the lattice parameters of the crystals at 303… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
