Volhard’s Method
Introduction Volhard’s method is a back titration technique used for the determination of chloride (Cl⁻), bromide (Br⁻), and iodide (I⁻) ions. It employs silver nitrate (AgNO₃) as a titrant to precipitate the halide ions, and the unreacted silver ions are then titrated with potassium thiocyanate (KSCN) using ferric ammonium sulfate as an indicator.
