Electrochemical Reaction Flashcards
galvanic cell
A cell in which chemical energy is converted to electrical
energy
oxidation in terms of electron (e-) transfer
Oxidation is a loss of electrons
oxidation in terms of electron (e-) transfer
Oxidation is a loss of electrons
reduction in terms of electron (e-) transfer:
Reduction is a gain of electrons.
Define oxidation in terms of oxidation numbers:
An increase in oxidation number
Define a reducing agent in terms of oxidation and reduction
A substance that is oxidised/loses electrons.
Anode
The electrode where oxidation takes place
Cathode
The electrode where reduction takes place
electrolyte
A substance of which the aqueous solution contains ions OR a
substance that dissolves in water to give a solution that conducts electricity
potential difference of a galvanic cell (Vcell)
Is related to the extent to
which the spontaneous cell reaction has reached equilibrium.
electrolytic cell
A cell in which electrical energy is converted into chemical
energy.
Electrolysis
The chemical process in which electrical energy is converted to
chemical energy OR the use of electrical energy to produce a chemical change
