• Noun:
  • Silver chloride precipitates as a white solid when a solution of silver nitrate is mixed with sodium chloride.
  • The early development of photography relied heavily on the light-sensitive properties of silver chloride.
  • In the laboratory, silver chloride is often used in analytical chemistry.

Advanced Usage

• "Silver chloride electrode": A type of reference electrode commonly used in electrochemistry, made by coating a wire with silver chloride.
  • The stability of the silver chloride electrode makes it ideal for pH measurements.
