what happens when they are exposed to water
fire hazard
If it's exposed to pure oxygen then nothing will happen. If it's exposed to air then the carbon dioxide in air will make it go cloudy. Lime water is the test for the presence of carbon dioxide.
All alkali metals react violently with water forming a hydroxide and hydrogen.
