Question

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

Tardigrade Admin · Accepted Answer

A water soluble complex with silver and dilute aqueous solution of NaCN is

N a [A g (CN)_{2})

In the cyanide process, the native silver is crushed and treated with aqueous NaCN solution and aerated.

4 A g + 8 N a CN + 2 H_{2} O + O_{2} \to 4 N a [A g (CN)_{2}] + 4 N a O H

A water soluble complex with silver and dilute aqueous solution of NaCN is Na[Ag(CN)2​) In the cyanide process, the native silver is crushed and treated with aqueous NaCN solution and aerated. 4Ag+8NaCN+2H2​O+O2​→4Na[Ag(CN)2​]+4NaOH

Q. Native silver metal forms a water soluble complex with a dilute aqueous solution of $N a CN$ in the presence of

A water soluble complex with silver and dilute aqueous solution of NaCN is $N a [A g (CN)_{2})$ In the cyanide process, the native silver is crushed and treated with aqueous NaCN solution and aerated.
$4 A g + 8 N a CN + 2 H_{2} O + O_{2} \to 4 N a [A g (CN)_{2}] + 4 N a O H$
