Question

In refining of silver the recovery of silver from silver nitrate solution involves displacement by copper metal .Give reason gor the same

Answer 1

In the electrolytic refining of any metal, the anode is the impure metal and the cathode is a strip of pure metal. The electrolyte is a salt of that particular metal which is being refined by electrolysis. Hence, in the refining of silver from silver nitrate, following reactions will occur at the anode and the cathode

Anode: Ag -----------> Ag+ + e- 

Cathode: Ag+ + e- -------> Ag

Here, displacement reaction with copper will not occur as it is not involved anywhere in the reaction.

However, as copper occurs before silver in the activity series, it can very much displace silver from its salt. This will be a displacement reaction. The equation is written as follows

 Cu + 2AgNO3 -------> Cu(NO3)2 + 2Ag

Answer 2

☺ Hello mate__ ❤

◾◾here is your answer...

Reaction :----

2AgNO2 (aq) + cu (s) ---> Cu(NO)3 (aq) + 2Ag (s)

Here AgNO2✒ silver nitrate

Cu(NO)3 ✒ Cooper nitrate !☺

✒ copper displaced the silver because it is more reactive.

I hope, this will help you.

Thank you______❤
