Question

In the refining of silver, the recovery of silver from silver nitrate solution involved displacement by copper metal. Write down the chemical equation of the reaction involved.

Answer 1

Answer:

Agcl(aq) + Cu(s) -------Cucl2(aq)+ Ag(s)

Explanation:

When Silver Nitrate Solution react with Cupper then Cupper Replace the Ag in Agcl and formed Cucl2 and Ag.

Answer 2

Chemical reaction in silver refining:

$C u_{s}+2 A g N O_{3(a q)} \rightarrow C u\left(N O_{3}\right)_{2(a q)}+2 A g_{(s)}$

Explanation:

• The refining is a process which is used to remove the impure metal present in the solution. In the above given process, the copper is the impurity found in silver nitrate. As a result of this process, only silver metal is obtained.
• There are many types of refining which includes hydrometallurgical and pyrometallurgical techniques.
• There are many steps involved in refining process. During extraction of ores, this is the final step involved as it produced pure form of the particular product.
