Electrochemistry Flashcards
1
Q
Redox reaction
A
A reaction involving the transfer of electrons
2
Q
Oxidation
A
The loss of electrons
3
Q
Reduction
A
The gain of electrons
4
Q
Oxidising agent
A
A substance that accepts electrons
5
Q
Reducing agent
A
A substance that donates electrons
6
Q
Electrolyte
A
A substance that can conduct electricity due to the presence of free (mobile) ions when molten or dissolved in solution
7
Q
Galvanic cell
A
A electrochemical cell that converts the chemical energy of spontaneous redox reactions into electrical energy
8
Q
Electrolytic cell
A
A electrochemical cell that uses electrical energy to cause a non-spontaneous redox reaction to occur. Thus, electrical energy is converted into chemical energy
9
Q
Anode
A
The electrode where oxidation takes place
10
Q
Cathode
A
The electrode where reduction takes place
