What is AgCl?
AgCl is the chemical formula for Silver Chloride that occurs in white crystalline form. The compound has no odor and occurs naturally as a mineral called chlorargyrite. It is well known for its low solubility in water. This compound can be synthesized using the aqueous solution Silver Nitrate ( AgNO3) and Sodium Chloride or Cobalt Chloride. AgCl immediately disintegrates into Ag and Cl upon exposure to light, and this is why it is used in making photographic papers.
