Give one word answer÷
lustrous white metal and it's ore is argentite.​

Answer 1

Answer:

Explanation:

Silver is extracted from the ore-argentite (Ag2SAg2S). The process of extraction of silver is called as cyanide process as sodium cyanide solution is used. The ore is crushed, concentrated and then treated with sodium cyanide solution. This reaction forms sodium argento cyanide Na[Ag(CN)2]Na[Ag(CN)2].

AgS+4NaCN⇌2Na[Ag(CN)2]+Na2S(1)(1)AgS+4NaCN⇌2Na[Ag(CN)2]+Na2S

The solution of sodium argento cyanide combines with zinc dust and forms sodium tetra cyanozicate and precipitated silver. This precipitated silver is called spongy silver.

Zn+2Na[Ag(CN)2]→Na2[Zn(CN)4]+2Ag(2)(2)Zn+2Na[Ag(CN)2]→Na2[Zn(CN)4]+2Ag

The spongy silver is fused with potassium nitrate to obtain pure silver. Then the silver obtained is purified by electrolytic process.
