Abstract The chloride present in an unknown soluble sample was precipitated into silver chloride through precipitation gravimetry. The colloidal silver chloride originally formed was converted to a crystalline solid by controlling certain parameters of the experiment such as temperature‚ pH of the solution‚ and concentration of AgNO3. Once the solid was large enough‚ it could be washed‚ filtered‚ and weighed. The percentage of chloride present was found to be 24.73695223 (±0.00000006) %.
