Electrochemistry and Redox reactions Flashcards
Define a redox reaction:
Redox reaction:
A reaction involving the transfer of electrons.
Define oxidation:
Oxidation is the loss of electrons.
Define reduction:
Reduction is the gain of electrons.
What is an oxidising agent?
An oxidising agent is a substance that accepts electrons.
What is a reducing agent?
A reducing agent is a substance that donates electrons.
What is an anode?
The anode is the electrode where oxidation takes place.
What is a cathode?
The cathode is the electrode where reduction takes place.
Define an electrolyte:
An electrolyte is a substance that can conduct electricity by forming free ions when molten or dissolved in solution.
What is brine?
Brine is a highly concentrated solution of sodium chloride (NaCl).
What are spectator ions?
Spectator ions are ions that do not take part in the transfer of electrons.
