reaches the Rayleigh instability limit, which leads to a ‘coulomb explosion’ of the alkali metal drop. Consequently, a new metal surface in contact with water is formed, which explains why the reaction does not become self-quenched by its products, but can rather lead to explosive behaviour....
In order to reveal to what extent tritium (H or T) can be incorporated into hydroxides, the isotope exchange reaction (OT-for-OH exchange reaction) between alkali metal hydroxides (MOH), where M means alkali metal, and HTO water was observed homogeneously at 70 C under equilibrium after ...

Thus, the validity of the ...
It is suggested that the sulphitonitroprusside ion exists in solution mainly as the ion pair, Fe(CN) 5NOSO 3M 3, where M is an alkali metal. The stability constants for this system are considered. The values obtained indicate that the degree of association is much lower than has ...

mixing a silica source, an alkali metal oxide source, an alumina source and water, to prepare a reaction mixture having a molar composition of M2O/SiO2 (M: alkali metal ion) of 0.07-0.14, H2O/SiO2 of 15-42 and SiO2/Al2O3 of 20-100; maintaining the reaction mixture at 180-210° C...
The platinum-catalysed hydrogen evolution reaction (HER) generally shows poorer kinetics in alkaline electrolyte and represents a key challenge for alkaline water electrolysis. In the presence of alkali metal cations and hydroxyl anions, the electrode–electrolyte (platinum–water) interface in an alkaline...
