Application
The silver chloride electrode is a common reference electrode in electrochemistry.
Silver chloride's low solubility makes it a useful addition to pottery glazes for the production of "Inglaze lustre".
Silver chloride has been used as an antidote for mercury poisoning, assisting in the elimination of mercury.
Silver chloride is used to make photographic paper since it reacts with photons to form latent image and via photoreduction in photochromic lenses, again taking advantage of its reversible conversion to Ag metal in bandages and wound healing products to create yellow, amber, and brown shades in stained glass manufacture as an infrared transmissive optical component as it can be hot-pressed into window and lens shapes as an antimicrobial agent in some personal deodorant products for long-term preservation of drinking water in water tanks
