The reaction between magnesium and water
It is possible to create a weak reaction between very clean magnesium ribbon and cold water. However, it is likely to only result in a few bubbles of hydrogen gas as the magnesium hydroxide produced is insoluble and forms a barrier on the surface of the magnesium. This barrier prevents further reaction.
Magnesium | + | water | → | Magnesium hydroxide | + | Hydrogen |
Mg | + | 2H2O | → | Mg(OH)2 | + | H2 |
