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
