Reaction of Alkali metals with water. Grade 10 SABIS ​ Generally: 2M(s) + 2H2O(l) → 2M+ (aq) + 2OH- (aq) + H2(g) alkali metal + water → alkali metal hydroxide + hydrogen Observations for the reaction of alkali metal with water:  Piece of metal floats (alkali metals have low density).  Piece of metal darts around.  A hissing sound is heard due to the evolution of a gas.  If red litmus paper is dipped in the solution, the paper turns blue due to the formation of the alkali metal hydroxide.  If few drops of phenolphthalein indicator are added to the water solution turns pink due to the formation of alkali metal hydroxide.  If the gas produced is tested with a lit splint, it burns with a squeaky pop sound.

Scientists explain the electrical conductivity of metals by:  the presence of electrons in the crystal that are loose, these electrons can move throughout the metallic crystal without specific attachment to particular atoms  and the ease of freeing one electron per atom. Grade 10 SABIS ​
