Classify the following reactions as oxidation or reduction:
making aluminium from aluminium oxide,
burning carbon in air,
copper oxide + carbon --> copper + carbon dioxide
carbon monoxide forming carbon dioxide.
Electron loss and gain
Oxidation is also a loss of electrons
eg Fe --> Fe2+ + 2e-
Reduction also the gain of electrons eg (when Fe
