Silver Nitrate and Sodium Chloride Precipitation

AgNO3 + NaCl → AgCl + NaNO3

Ikhtisar

Silver nitrate reacts with sodium chloride to form an insoluble white precipitate of silver chloride and soluble sodium nitrate. This is a classic precipitation reaction and the basis of the chloride ion test in analytical chemistry. The white precipitate turns purple in light due to photodecomposition.
