Q. Metallic silver may be obtained from $AgCl$ by
A) Heating it in the current of $H_{2}$
B) Fusing it with sand
C) Treating with carbon monoxide
D) Fusing it with ${Na}_{2}{CO}_{3}$
Explanation
(d)
On fusing $AgCl$ with ${Na}_{2}{CO}_{3}$, metallic silver is obtained.
$2AgCl\ + \ {Na}_{2}{CO}_{3}\ \overset{Fuse}{\rightarrow}\ 2Ag\ \downarrow \ + \ 2NaCl\ + \ {CO}_{2}\ + \ \frac{1}{2}O_{2}$
