What is a Silver chloride (AgCl)?

Silver chloride (AgCl) is an inorganic compound consisting of silver and chlorine. It is one of the well-known silver compounds, and its chemical formula is AgCl. Silver chloride is important in various applications, including photographic films and optical devices. One of its distinctive properties is its extremely low solubility in water, which makes it stable under normal conditions and resistant to dissolution unless exposed to strong acids or bases. Silver chloride is also photosensitive. When exposed to UV or visible light, it decomposes, and silver precipitates out. This property is exploited in the photographic development process. Silver chloride is used in silver-based films, where light exposure causes the silver particles to form the image.

Moreover, silver chloride has uses in electrochemical applications, such as in silver batteries and sensors. It plays a role in redox reactions and is crucial in water quality testing and chemical analysis. Additionally, due to silver's known antibacterial properties, silver chloride is used in some antimicrobial products.
