The correct Answer is:A Alkali metals are better reducing agents than hydrogen. When alkali metals react with water hydrogen gas is liberated . Show More | ShareSave Class 12CHEMISTRYGENERAL PRINCIPLES AND PROCESSES OF ISOLATION OF ELEMENTS ...
The alkali metals have 1 valence electron and are the most reactive metals. How do alkali metals react with water? All alkali metals react violently with water, releasing hydrogen gas and forming hydroxides. The hydroxides give alkaline solutions. ...
Alkali metals can react explosively with water and it is textbook knowledge that this vigorous behaviour results from heat release, steam formation and ignition of the hydrogen gas that is produced. Here we suggest that the initial process enabling the a
The alkali metals react with water in the caustic solution in a controlled reaction while steam dilutes the hydrogen formed by the reaction to a safe level.Leroy C. Lewis

Alkali metals can react explosively with water and it is textbook knowledge that this vigorous behaviour results from heat release, steam formation and ignition of the hydrogen gas that is produced. Here we suggest that the initial process enabling the alkali metal explosion in water is, however,...
alkali metals, metals found in Group 1 of the periodic table. Compared to other metals they are soft and have low melting points and densities. Alkali metals are powerful reducing agents and form univalent compounds. All react violently with water, releasing hydrogen and forming hydroxides. They...
What happens when alkali metals react with molecular hydrogen? 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...

The different alkali metal oxides can be distinguished by reaction with water.The superoxides reacts with CO2 and give oxygen gas.The stability of per and superoxides is based upon that larger cation can stablise larger anion, due to larger lattice energy. Alkali metals dissolve in liquid amm...
