NaCl(aq) + AgNO3(aq) → AgCl(s) + NaNO3(aq)
In this reaction, the sodium and chloride ions from the sodium chloride solution combine with the silver and nitrate ions from the silver nitrate solution to form insoluble silver chloride. The white solid that forms is silver chloride, which is characterized by its low solubility in water. The sodium and nitrate ions remain in the solution as sodium nitrate, which is soluble in water.
The formation of silver chloride can be observed as a white precipitate when the two solutions are mixed. The precipitate can be separated from the solution by filtration or centrifugation. Silver chloride is a light-sensitive compound and can turn dark upon exposure to light.
