Question

To obtain silver from silver amalgam it is heated in vessel which is made up of –
(A) Cu
(B) Fe
(C) Ni
(D) Zn

Answer 1

To answer this question, we first need to understand what silver is. Silver (Ag), a white shiny metal renowned for its aesthetic beauty and electrical conductivity, is a chemical element. Silver belongs to Group 11 (Ib) and Period 5 of the periodic table, and its physical and chemical properties are halfway between those of copper (Period 4) and gold (Period 6).

Complete answer:
Amalgam - A mercury amalgam is a mixture of mercury and another metal. Depending on the percentage of mercury, it can be a liquid, a soft paste, or a solid. Gold-mercury amalgams are employed in the extraction of gold from ore, and silver-mercury amalgams are utilized in dentistry.
Amalgams are used to construct dental fillings, to bind valuable metals in order to isolate them later, and to create mirror coatings. Contact with an amalgam can release a small amount of mercury, much like other elements in other alloys.
To obtain silver from silver amalgam, it is heated in a vessel of Fe rather than a vessel of Cu, Ni, or Zn because silver amalgam does not react with Fe in a Fe vessel, but it does in other vessels.
So, we conclude that iron vessels should be used.
So, the final answer is option(B) i.e., Fe.

Note:
Amalgam fillings are considered to be safe. These fillings have been studied extensively and proved to be an effective and long-lasting therapy for dental decay. Mercury, silver, tin, and copper are used to make amalgam, or silver fillings. Other metals may also be present in amalgam fillings in some situations.
