Cobalt chloride is blue when dry but turns pink in the presence of water. in dry weather due to the peculiar properties of cobalt chloride, indicating. Suspected of causing genetic defects if inhaled May cause cancer. A system at chemical equilibrium is one in which the concentrations of all the. When the simple weather forecasting device is in use, the indicator sign is. May cause allergy or asthma symptoms or breathing difficulties if inhaled. Influence of the solvent composition on the complex stability and thermochromism was also discussed.H302+H332-H317-H318-H334-H341b-H350-H360-H410 standard enthalpy, entropy and Gibbs energy, were calculated for all complexation reactions. Based on these stability constants, the thermodynamic data, i.e. The overall stability constants of all formed complexes were calculated using a non-linear regression program at different temperatures: 308.15, 318.15, 328.15, 338.15 and 348.15 K. Absorption spectra have been investigated in the visible spectral range 400–800 nm at two different temperatures (298.15 and 323.15 K). In all binary mixtures the mole ratio of ammonium nitrate to the second component of the system was 1:3 and they were studied as suitable solvents for the formation of cobalt(II) chloro-complexes. The selected organic components were formamide (FA), N-methylformamide (NMF), N, N-dimethylformamide (DMF) and dimethylsulphoxide (DMSO). In this work, the thermochromic behaviour of cobalt(II) chloro-complexes was investigated by VIS–spectroscopy in four different ammonium nitrate+organic component based solvents and in ammonium nitrate+calcium nitrate tetrahydrate melt. Hence, the increase of absorbance with temperature acts as an auto-regulated shading protection from overheating.
The well known fact that cobalt(II) halide complexes in various media undergo changes of co-ordination, absorbance and colour with the increase of temperature was combined with the low melting point of new materials suitable for simultaneous control of temperature and light intensity.
