Silver chloride is a white color when it is in solid form. It is a crystal, but when it is used in the application of stained glass it turns into a dark amber color.
When silver chloride is put into sunlight or is heated up, it transforms into different substances. These substances can then be used separately and can work independently of each other. As the name implies, it turns into silver and chlorine. The sunlight as well as the heat need to be affecting the silver chloride for long periods of time and at great intensities in order for the substance to transform.
Other than in stained glass applications and photographic uses, silver chloride has many different uses. It can be used in seawater activated batteries as a cathode. It is a powerful substance and one that is organic, which allows it to be used in many different applications.
