What is electrochemistry?

Back

Electrochemistry is the branch of chemistry that deals with the relationship between electrical energy and chemical reactions, particularly those involving the transfer of electrons.

Front

What is oxidation in electrochemistry?

Back

Oxidation is the process in which an atom, ion, or molecule loses electrons, resulting in an increase in oxidation state.

Front

What is reduction in electrochemistry?

Back

Reduction is the process in which an atom, ion, or molecule gains electrons, resulting in a decrease in oxidation state.

Front

What is a standard reduction potential?

Back

Standard reduction potential is a measure of the tendency of a chemical species to be reduced, measured in volts (V) under standard conditions.

Front

What does a negative standard reduction potential indicate?

Back

A negative standard reduction potential indicates that the species is less likely to be reduced and is more likely to be oxidized.

Front

What is the relationship between oxidation and reduction?

Back

Oxidation and reduction are complementary processes; when one species is oxidized, another species must be reduced.

Front

What is an electrochemical cell?

Back

An electrochemical cell is a device that converts chemical energy into electrical energy or vice versa through redox reactions.

Front

What is the anode in an electrochemical cell?

Back

The anode is the electrode where oxidation occurs, and it is the source of electrons in the external circuit.

Front

What is the cathode in an electrochemical cell?

Back

The cathode is the electrode where reduction occurs, and it is where electrons are accepted from the external circuit.

Front

How do electrons flow in an electrochemical cell?

Back

Electrons flow from the anode to the cathode through the external circuit.
