Dangerous experiments with
sodium metal. Sodium metal is put in dilute hydrochloric acid. The heat,
produced in this reaction, ignites the hydrogen, formed in this
reaction. This leads to a loud bang!
Electrolysis of water --
detonating gas. Water is decomposed by means of electrolysis of a
dilute sulphuric acid solution. The resulting gases are mixed and the
impressive explosive power of this gas mix is demonstrated.
