During the electrolysis of molten chlorides of metals like sodium, magnesium, and calcium, the metals are deposited at the cathode, where reduction occurs, while chlorine ions are oxidized at the anode, liberating chlorine gas.

Electrolytic reduction is used for obtaining metals high up in the reactivity series because traditional methods such as heating with carbon are ineffective due to the high affinity of these metals for oxygen. Electrolytic reduction allows for the extraction of ...

Metals like sodium, magnesium, and calcium are obtained by electrolytic reduction. The process involves electrolyzing their molten chlorides, where the metals are deposited at the cathode (negatively charged electrode) while chlorine is liberated at the anode (positively charged electrode).

Metals high up in the reactivity series, such as sodium, magnesium, calcium, and aluminium, cannot be obtained from their compounds by heating with carbon because these metals have a stronger affinity for oxygen than carbon, making carbon ineffective as a ...

The thermit reaction, such as the reaction of iron(III) oxide (Fe2O3) with aluminium, is utilized in practical applications such as joining railway tracks or repairing cracked machine parts by producing molten iron as a result of the highly exothermic reaction.

The large amount of heat evolved in displacement reactions is significant because it can cause the metals involved to be produced in the molten state.

Displacement reactions involving highly reactive metals and metal compounds are highly exothermic because a large amount of heat is released during the reaction.

The process of obtaining metals from their compounds involves reduction, where metal oxides are reduced to their elemental form. This process is a chemical reaction involving the transfer of electrons, which is characteristic of reduction reactions.

Highly reactive metals function as reducing agents by displacing metals of lower reactivity from their compounds through displacement reactions. They donate electrons to the metal ions, causing them to be reduced to their elemental form.

Some examples of highly reactive metals used as reducing agents include sodium, calcium, and aluminium.
