Question

Alkali metals react with water to form:

  1. Hydrogen and metal hydroxide 
  2. Hydrogen and metal oxide 
  3. Metal hydroxide and oxygen 
  4. Metal oxide

hintHint:

Metal hydroxide and hydrogen.

The correct answer is: Hydrogen and metal hydroxide 


    Alkali metal attain +1 charge in the reactions. When alkali metals react with water they form metal hydroxide and hydrogen gas.
    Alkali metal + water rightwards arrow metal hydroxide + hydrogen
         M + H2Orightwards arrowMOH + H2
