AgCl quickly darkens on exposure to light by disintegrating into elemental chlorine and metallic silver. This reaction is used in photography and film and is the following: [ 5 ] Cl − + hν → Cl + e − (excitation of the chloride ion, which gives up its extra electron into the conduction band)
Silver hypochlorite is a chemical compound with the chemical formula Ag O Cl (also written as AgClO). It is an ionic compound of silver and the polyatomic ion hypochlorite. [1] [2] The compound is very unstable and rapidly decomposes. [3]
When silver nitrate (AgNO 3) is added to a solution of potassium chloride (KCl) the precipitation of a white solid (AgCl) is observed. [5] [6] + + The ionic equation allows to write this reaction by detailing the dissociated ions present in aqueous solution.
A silver halide (or silver salt) is one of the chemical compounds that can form between the element silver (Ag) and one of the halogens.In particular, bromine (Br), chlorine (Cl), iodine (I) and fluorine (F) may each combine with silver to produce silver bromide (AgBr), silver chloride (AgCl), silver iodide (AgI), and four forms of silver fluoride, respectively.
The ionic strength of a solution is a measure of the concentration of ions in that solution. Ionic compounds, when dissolved in water, dissociate into ions. The total electrolyte concentration in solution will affect important properties such as the dissociation constant or the solubility of different salts. One of the main characteristics of a ...
AgCl (s) ⇌ Ag + (aq) + Cl − (aq) However, there is a limit to how much salt can be dissolved in a given volume of water. This concentration is the solubility and related to the solubility product, K sp. This equilibrium constant depends on the type of salt (AgCl vs. NaCl, for example), temperature, and the common ion effect.

Ionic radius, r ion, is the radius of a monatomic ion in an ionic crystal structure. Although neither atoms nor ions have sharp boundaries, they are treated as if they were hard spheres with radii such that the sum of ionic radii of the cation and anion gives the distance between the ions in a crystal lattice.
