Electrochemical Reactions Flashcards
galvanic cell
a cell in which chemical energy is converted to electrical energy.
Oxidation( in terms of electron transfer)
a loss of electrons
Reduction ( in terms of electron transfer )
a gain of electrons
Oxidation (in terms of oxidation)
an increase in oxidation number
Reduction ( in terms of oxidation)
a decrease in oxidation number
Oxidising agent
a substance that is reduced/gains electrons
Reducing agent
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)
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
