Native silver metal forms a water solubl...

Native silver metal forms a water soluble complex with a dilute aqueous solution of NaCN in the presence of

A

nitrogen

B

oxygen

C

carbon dioxide

D

argon

Text Solution

Verified by Experts

The correct Answer is:
B
Ag dissociates in a solution of NaCN in the presence of air, and forms sodium argentocyanide.
`4Ag + 8NaCN + 2 H_(2)O + O_(2) rarr 4Na [Ag(CN)_(2)] + 4NaOH`
Hence, (B) is the correct answer.
