A. Cara Industri
B. Cara Laboratorium
1. Elektrolisis air yang sedikit diasamkan

2H2O (l) ® 2H2 (g) + O2 (g)

 

1.
Logam (golongan IA/IIA) + air
2K(s) + 2H2O(l) ® 2KOH (aq) + H2 (g)
Ca (s) + 2H2O (l) ® Ca(OH)2 (aq) + H2 (g)
2. 3Fe(pijar) + 4H2O « Fe3O4 (s) + 4H2(g)
2.
Logam dengan Eok o > O + asam kuat encer
Zn (s) + 2HCl (aq) ® ZnCl2 (aq) + H2 (g)
Mg (s) + 2 HCl (aq) ® MgCl2 (aq) + H2(g)
3. 2C(pijar) + 2H2O (g) ® 2H2 (g) + 2CO (g)
3.
Logam amfoter + basa kuat
Zn (s) + NaOH(aq) ® Na2ZnO2 (aq) + H2(g)
