Electrolytic refining is significant in metallurgy because it allows for the production of high-quality, pure metals suitable for various industrial applications. This process is widely used for refining metals such as copper, silver, and gold.

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).

Yes, cinnabar (HgS) is an ore of mercury. When heated in air, cinnabar is converted into mercuric oxide (HgO). Further heating of mercuric oxide results in its reduction to mercury, the pure metal.
