Distinguish between the following:
$(i)$ Electrolytic reduction and electrolytic refining
$(ii)$ Mineral and ore
$(iii)$ Alloys and amalgams

(N/A) $(i)$

Electrolytic reduction	Electrolytic refining
It is a process of obtaining metals from their molten chlorides or oxides by electrolysis. The metals are deposited at the cathode,whereas chlorine or oxygen is liberated at the anode.	It is a process of refining impure metals obtained by any reduction process. The impure metal is taken as the anode,pure metal as the cathode,and a metal salt solution as the electrolyte.

$(ii)$ Minerals are naturally occurring elements or compounds in the Earth's crust. Ores are those minerals from which metals can be extracted profitably and conveniently.
$(iii)$ An alloy is a homogeneous mixture of two or more metals or a metal and a non-metal. An amalgam is a specific type of alloy in which one of the components is mercury $(Hg)$.
