In a concentration cell, the potential difference arises due to different concentrations of the same species.

In a Daniell cell, zinc is oxidized.

In a galvanic cell, oxidation occurs at the anode.

Reduction refers to the gain of electrons in a chemical reaction.

The effect of increasing temperature on cell potential depends on the reaction and its enthalpy change.

The effect of temperature on cell potential depends on the reaction and its enthalpy change.

The main function of a salt bridge is to maintain charge balance by allowing ions to flow.

The Nernst equation is used to determine the cell potential under non-standard conditions.

The cathode is where reduction occurs, gaining electrons in the process.

The primary function of a salt bridge is to maintain charge balance by allowing ions to flow between the half-cells.

During discharge, the primary reaction in a lead-acid battery is Pb + PbO2 + 2H2SO4 → 2PbSO4 + 2H2O.

The salt bridge maintains charge balance by allowing ions to flow between the two half-cells.

In an electrochemical cell, reduction occurs at the cathode.

The standard electrode potential of the hydrogen electrode is defined as 0.00 V.

The unit of electric charge is the Coulomb.

The unit of electrical charge is the Coulomb.

A fuel cell converts chemical energy directly to electrical energy without combustion.

The zinc-carbon battery is a primary cell, while the others are secondary cells.

Zinc is used as the anode in a Daniell cell.

Aluminum is commonly used as an anode in electrolysis due to its high reactivity.

Copper cannot be used as an anode in a galvanic cell because it is less reactive than zinc.

Electrolysis involves the decomposition of a compound using electrical energy.

Electrolytic cells require an external power source to drive the non-spontaneous reactions.
