Electrolysis of distilled water
In the absence of dissolved electrolytes, water will not conduct electricity, so no electrolysis occurs.
electrochemistry
Electrolysis of tin(IV) chloride
Electrolysis of a tin(IV) chloride solution produces oxygen at the anode, hydrogen and tin(II) ion at the cathode.
Electrolysis of tin(II) chloride
Electrolysis of a tin(II) chloride solution produces oxygen at the anode and tin metal at the cathode.
Electrolysis of sodium nitrate
Electrolysis of a sodium nitrate solution produces oxygen at the anode and hydrogen at the cathode.
Electrolysis of magnesium nitrate
Electrolysis of a magnesium nitrate solution produces oxygen at the anode and hydrogen at the cathode.
Electrolysis of a sodium sulfate solution
An electric current is passed through a sodium sulfate solution. Gases are collected at the electrodes are tested for pH.
