Answer 1

Answer:

Ag + Cl gives Ag+ and Cl-

Explanation:

When the air silver chloride is exposed to air then the decomposition takes place which breaks the Silver chloride into silver and chloride. When the decomposition takes place the white colour of Silver chloride changes to Grey due to the formation of silver metal.

Answer 2

Answer:

White silver chloride turns Grey.

Explanation:

In the presence of sunlight the silver chloride turns grey to form metallic silver and chlorine gas.

Equation:
