electrolysis

Electrolysis of a barium nitrate solution produces oxygen at the anode and hydrogen at the cathode.

Electrolysis of a magnesium nitrate solution produces oxygen at the anode and hydrogen at the cathode.

Electrolysis of a sodium nitrate solution produces oxygen at the anode and hydrogen at the cathode.

Electrolysis of a tin(II) chloride solution produces oxygen at the anode and tin metal at the cathode.

An electric current is passed through a sulfuric acid solution. Gases collected at the electrodes are tested.

This animation simulates the electrolysis of a neutral aqueous solution.

Electrolysis of a hydrochloric acid solution produces oxygen at the anode and hydrogen at the cathode.

In aqueous hydrochloric acid, the electrolyzed solution is acidic at both electrodes.

Electrolysis of a sodium hydroxide solution produces oxygen at the anode and hydrogen at the cathode.

In aqueous sodium hydroxide, the electrolyzed solution is basic at both electrodes.
