ELECTROCHEMIS
TRY
, TERMINOLOGY
• Oxidation-the loss of electrons /an increase in oxidation number
• Reduction- the gain of electrons/ a decrease in oxidation number
• Oxidising agent - a substance that is reduced/gains electrons OR
a substance that undergoes reduction
• Reducing agent - a substance that is oxidized/loses electrons OR
a substance that undergoes oxidation
, • Electrode - a solid electric conductor through which an electric
current enters or leaves an electrolyte
• Anode - the electrode where oxidation takes place
• Cathode - the electrode where reduction takes place
• Galvanic cells - Is the electrochemical cell that converts
chemical energy to electrical energy.
• electrolytic cells - Is the electrochemical cell that coverts
electrical energy to chemical energy.
