Silver Chloride Precipitation

AgNO3 + NaCl → AgCl↓ + NaNO3

अवलोकन

Silver nitrate reacts with sodium chloride to form a white curdy precipitate of silver chloride. AgCl has a very low Ksp of 1.8 × 10⁻¹⁰, making it essentially insoluble. The precipitate turns purple in light due to photodecomposition of AgCl to silver metal and chlorine. This is the basis of the chloride ion test.
