how can we make hydrogen ?
1. I method:
You can get hydrogen gas by reacting hydrochloric acid with zinc.

Zinc + Hydrochloric Acid ? Zinc Chloride + Hydrogen
Zn (s) + 2HCl (l) ? ZnCl2 (l)+ H2 (g)

  • hydrochloric acid (muriatic acid)
  • zinc granules (or iron filings or strips of aluminum)
Hydrogen gas bubbles will be released as soon as the acid and zinc are mixed. Be very careful to avoid contact with the acid. Also, heat will be given off by this reaction.
2. II Method:
  • sodium hydroxide (found in certain drain clog removers)
  • aluminum (included in the drain removal products or you can use foil)
Aluminum + Sodium Hydroxide ? Hydrogen + Sodium Aluminate
2Al (s) + 6NaOH (aq) ? 3H2 (g) + 2Na3AlO3 (aq)

This is an extremely easy method of making homemade hydrogen gas. Simply add some water to the drain clog removal product! The reaction is exothermic, so use a glass bottle (not plastic) to collect the resulting gas.
