Reaction with chlorine Reaction with oxygen What are alkali metals? The alkali metals are the six metals of Group 1 in the Periodic Table – lithium, sodium, potassium, rubidium, ceasium (cesium), and francium. Only lithium, sodium and potassium are safe enough to keep in the school lab. ...

The reaction of zinc chloride with borohydrides of the alkali metals in organic solventsIn the interaction of zinc chloride with alkali metal borohydrides in organic solvents (diethyl ether, THF, diglyme), chlorine is replaced by the borohydride ion, with the formation of zinc borohydride. In ...
These species, upon reaction with HCl, form alkali chlorides which can condensate and form deposits on the metal surface. Corrosion reactions involving solid phase Cl-species in deposits have been associated with alkali chlorides, especially KCl in the case of biomass firing. Nielsen et al. [20]...

Alkali Metals: Alkali metals are elements of group 1.They are called alkali metals because the hydroxides they form on reaction with water, is highly alkaline in nature. The elements listed below constitute group 1 elements and are collectively considered as alkali metals. ...

Alkali metal chlorites are produced by the reaction of chlorine dioxide with an alkali metal amalgam in a reaction mixture where the pH is maintained at from about 9.5 to about 11.5 by providing an excess of the alkali metal to the chlorine dioxide of at least 10 mole percent. Alkali metal...
with the standard NaCl/CaCl2,/BaCl2electrolyte. When in the form of sodium fog, sodium can partially migrate to the anode where the sodium is re-oxidized or reacts with chlorine to form NaCl. Sodium fog can also migrate to the surface of the molten electrolyte, which is exposed to air, ...
