Abstract:
The high-resolution quasi-elastic neutron scattering (QENS) technique has been applied to study the translational diffusion of methanol protons in pure methanol (MeOH) at 223 and 297 K, and in 0.3 and 1.3 molal non-aqueous electrolyte solutions (NAESs) of NiCl2 in methanol at 297 K. Molecular dynamics (MD) simulations, in conjunction with the present QENS results and our previously published structural results obtained by neutron diffraction isotopic substitution (NDIS) experiments, have been carried out in the NVT ensemble to explore the particle dynamics and microscopic structures of the experimentally investigated systems. The simulated structure of the ∼1.35 molal NiCl2-MeOH NAES has been compared with the structures of Ni2+ and Cl- coordination shells in ∼1.4 molal NAES obtained earlier by the NDIS technique.

SN2 Reaction: Kinetics
In a chemical reaction, a relationship exists between the concentration of reactants and the rate at which the reaction proceeds. The study to measure this relationship is known as the kinetics of a chemical reaction. Kinetic studies are used to deduce the rate law of a chemical reaction, which provides information about the species involved during the transition state of the rate-determining step. Thus, kinetic studies help to derive the mechanism of a...

Precipitation Gravimetry
In determining nickel by gravimetric analysis, a precipitant of ethanolic dimethylglyoxime is added to a hot nickel salt solution. This is quickly followed by the dropwise addition of dilute ammonia solution until precipitation occurs. A...
