Galvanic and Electrolytic Cells

Front

What is a Galvanic Cell?

Back

A Galvanic Cell is an electrochemical cell that converts chemical energy into electrical energy through spontaneous redox reactions.

Front

What is the role of the anode in a Galvanic Cell?

Back

The anode is the electrode where oxidation occurs and is negatively charged.

Front

What is the role of the cathode in a Galvanic Cell?

Back

The cathode is the electrode where reduction occurs and is positively charged.

Front

What is a standard electrode potential?

Back

Standard electrode potential is a measure of the tendency of a chemical species to be reduced, measured in volts.

Front

Which element is the strongest reducing agent?

Back

Lithium (Li) is the strongest reducing agent among the given options.

Front

What is the half-reaction occurring at the cathode in the reaction Zn + HgO → ZnO + Hg?

Back

The half-reaction at the cathode is HgO + 2 e- → Hg + O^2-.

Front

What is the function of the salt bridge in a Galvanic Cell?

Back

The salt bridge allows the flow of ions between the two half-cells, maintaining electrical neutrality.

Front

How do you calculate the cell potential of a voltaic cell?

Back

The cell potential is calculated using the standard electrode potentials of the half-reactions.

Front

What is an Electrolytic Cell?

Back

An Electrolytic Cell is an electrochemical cell that uses electrical energy to drive a non-spontaneous chemical reaction.

Front

What occurs at the anode of an Electrolytic Cell?

Back

Oxidation occurs at the anode of an Electrolytic Cell.
