Silver metal is extracted from Ag(2) S b...

Silver metal is extracted from `Ag_(2) S` by cyanide process. The one is concentrated through froth floation process. The concentrated ore is the leached and solution is r ed with reducing agents to get spongy silver which then purified by fusion with an oxidant followed by electrolysis.
Which of the following statements about electrolytic refining of silver is not true

A

Anode consists of impure silver

B

cathode consists of pure silver

C

Electrolytic solution consists of `AgNO_(3) and HNO_(3)`

D

Elecipitated solution consists of `AgNO_(3) and HCl`

Text Solution

Verified by Experts

The correct Answer is:
C
Pure Ag is obtained by the electrolysis of `AgNO_(3)` sol containing 10% `HNO_(3)` and using the impure silver as anode and pure silver plate as cathode.

Electrolysis is the process in which electrical energy is converted to chemical energy. In electrolyte cell, oxidation takes place at anode and reduction at cathode. Electrode process depends on the electrode taken for electrolysis. Amount of substance liberated at an electrode is directly proportionation to the amount of charge passed through it. The mass of substance liberated at electrode is calculate using the following realation : m=(itE)/(96500) Here, E represent the equivalent mass and 96500 C is called the faraday constant. Faraday (96500 C) is the charge of 1 mole electron i.e., 6.023 xx 10^(23) electrons, it is used to liberate on gram equivalent of the substance. The passage of current liberates H_2 at cathode and Cl_2 at anode. The solution is
