Question

State the method using from the purification of crude metal explain in which context these methods are used?

Answer 1

Answer:

the process of obtaining the pure metal from the impure metal is called refining of the metals

Various methods of adopted in purification of metals

DISTILLATION: the method is very use ful for purification of boiling metals like zibcand mercury containing high boiling metals as impurities

POLING:the molten metal is stirred with logs of green wood

LIQUATION:low melting metals like yin can be made to flow on a slopey surface to seperate it from high melting impurities

ELECTROLYTIC REFINING: in this method, the impure metals is nade to act as anode

A strip of the same metal in pure from is used cathode

the metals constitution impurity goes as the anode mud

Answer 2

Answer:

Refining of metals is the process of separating the pure metal from the impure metal.

Explanation:

The following are some popular techniques for metal purification:

• Distillation - The technique is highly helpful for removing high boiling metal impurities from boiling metals like zirconium and mercury.
• Poling - Green wood logs are used to stir the molten metal.
• Liquation - To separate it from high melting impurities, low melting metals like yin can be made to flow on a sloped surface.
• Electrolytic Refining - The impure metals are employed as the anode in this approach, and a strip with the same metal that is pure is utilized as the cathode. Anode mud is a representation of the metals' constitution impurity.
• Vapour phase refining - In order to recover the metal in this sort of purification, the metal should quickly break down into a volatile compound when a reagent is present.
• Chromatographic method - This process involves dispersing the crude mixture into a liquid or gaseous medium. An adsorbent is used to pass this medium through it.

Thus, refining is a process used to get high purity metals by removing impurities.
