Question

Distinguish between the following:
(a) Electrolytic reduction and Electrolytic refining.
(b) Minerals and Ores
(c) Alloy and Amalgam

Answer 1

electrolytic reduction is extracting metals of high reactivity from their ores and electrolytic refining is removing earthly and siliceous impurities from the ores
b. the elements are compounds which occur naturally in the earth crust are called minerals and the minerals in which metals are present in profitable amount are called ores
c. alloy is homogeneous mixture of a metal and a nonmetal or two metals and amalgam is an alloy in which one constituent is mercury

Answer 2

electrolytic reduction is used for the extraction of metals from their oxides..whereas electrolytic refining is used to purify the extracted metal if any impurity present...

minerals are those substamce found in the earth crust which contain metals either in the free state or in combined state.....whereas ore is the mineral from which metals can be extracted convinently and profitably...all ores are minerals but all minerals are not ores..

alloy is a homogeneous mixture of two or more metals OR a metal and a non metal ...whereas amalgum is a alloy whose one constituent is mercury...or it is a mixture of mercury and a metal....

hope it will help uhh
