The Confirmatory Test for Lead is a laboratory procedure used to detect the presence of lead ions (Pb²⁺) in inorganic salts such as lead nitrate. It involves preliminary solubility and acid tests followed by specific confirmatory reactions using reagents like sodium hydroxide, potassium iodide, potassium chromate, and sulfuric acid. These reactions produce characteristic precipitates, enabling accurate identification and differentiation of lead from other cations.
