Electrolysis of tin(II) chloride
Electrolysis of a tin(II) chloride solution produces oxygen at the anode and tin metal at the cathode.
oxidation/reduction
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 aluminum nitrate
Electrolysis of an aluminum nitrate solution produces oxygen at the anode and hydrogen at the cathode.
Electrolysis of potassium nitrate
Electrolysis of a potassium 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.
Reaction of magnesium with carbon dioxide
The reaction of magnesium with carbon dioxide (dry ice) is demonstrated. Despite the absence of air, the magnesium continues to glow.
Simple redox titration
A simple redox titration (hydrogen peroxide with permanganate) is performed.
Redox titration animation
This animation demonstrates aspects of the stoichiometry of a redox titration.
Reaction of sodium and chlorine
A small piece of sodium metal is placed in a flask containing chlorine gas. Initially, no reaction is observed, but addition of a drop of water to the sodium initiates a vigorous reaction. Includes close-up replay of reaction.
