Best Answer

Electrolysis of water produces hydrogen and oxygengases at different electrodes.

2H2O(l) --> 2H2(g) + O2(g)

Hydrogen is collected at the cathode.
Oxygen is collected at the anode.

If you're electrolyzing water, and if you're doing this in class you almost certainly are, it's

2H2O -> 2H2 + O2

You can electrolyze a lot of things. In industry, they electrolyze salt.

Chloralkali process: produces chlorine, hydrogen gas and sodium hydroxide

2NaCl + 2H2O -> Cl2 + H2 + 2NaOH

Solvay process: produces sodium carbonate and calcium chloride

2NaCl + CaCO3 -> Na2CO3 + CaCl2

Mannheim process: produces hydrochloric acid and sodium sulfate

2NaCl + H2SO4 -> Na2SO4 + 2HCl

Cathode: NH4+(aq) + MnO2(s) + H2O(l) + e- → Mn(OH)3(s) + NH3(aq)

Anode: Zn(s) → Zn2+(aq) + 2e-

NH4Cl(aq) + MnO2(s) + H2O(l) + Zn(s) → Mn(OH)3(s) + NH3(aq) + Zn2Cl(aq)
