The Ag will weigh less than the AgCl and your results will be poor because photodecomposition releases Cl2 from AgCl according to the equation 2AgCl ==> 2Ag + Cl2.
A chemical reaction in which photons break down the molecules of a chemical compound is known as photodissociation, photolysis, photodecomposition, or photofragmentation. It is described as occurring when one or more photons interact with a single target molecule. It is not just visible light that causes photodissociation. a chemical compound being broken down using photons or light energy. For instance, under the influence of light, the water molecule underwent photodecomposition during photosynthesis. The hydrogen binds to an acceptor as a result of photon absorption, releasing the oxygen. With the help of polymer stabilizers, which are frequently used, photodegradation of plastics and other materials can be prevented. Antioxidants are among these additions; they stop the process of deterioration.
