Hydrolysis of cadmium cation in different ionic strength
The hydrolysis of cadmium nitrate was studied spectrophotometrically at different ionic strengthsof sodium perchlorate in a wide pH range, 1-12, and at 25 C. Least squares calculations areconsistent with the formation of M(OH)+, M(OH)2, M(OH)3- and M(OH)42- species, which M isCd2+. The dependency on ionic strength in the background electrolyte solutions was taken intoaccount by using a Debye-Hu...
متن کاملAnalytic Behaviour of Competition among Three Species
We analyse the classical model of competition between three species studied by May and Leonard (SIAM J Appl Math 29 (1975) 243-256) with the approaches of singularity analysis and symmetry analysis to identify values of the parameters for which the system is integrable. We observe some striking relations between critical values arising from the approach of dynamical systems and the singularity ...

متن کاملCation electrochemical stability in chloroaluminate ionic liquids.
The electrochemical stability of 10 organic cations, which can be used in ionic liquids (IL), was investigated as solutes in acetonitrile (ACN). The stability of three of the salts, BenMe2EtNCl (salt III), 1-butyl-2-methyl pyrrolidium chloride (salt VI), and its structural isomer, BuMe2ProNCl (salt VII), were also compared in chloroaluminate ILs. The chloroaluminate ILs of salts VI and VII are ...
متن کاملUltrafast dynamics of pyrrolidinium cation ionic liquids.
We have investigated the ultrafast molecular dynamics of five pyrrolidinium cation room temperature ionic liquids using femtosecond optical heterodyne-detected Raman-induced Kerr effect spectroscopy. The ionic liquids studied are N-butyl-N-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide P14+/NTf2-), N-methoxyethyl-N-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide P1EOE+/NTf2-), N-et...
