In the extraction of silver from argentite ore the ore is treated witlh dilute solution of NaCN in water in the presence of Y, whereby the following reaction takes place `Ag_(2)X + 4NaCN +2Y rarr 2Na [ Ag(CN)_2] + Na_2XO_4`
X and Y in this reaction are represented by

A

Cl and S

B

S and `O_2`

C

`O and O_2`

D

`O and S`

Text Solution

Verified by Experts

The correct Answer is:
B
`Ag_2S + 4NaCN + 2O_2 rarr 2Na [Ag(CN)_2] + Na_2SO_4`
X is S and Y is `O_(2)`
