Gravimetric analysis is a method in quantitative analysis where an unknown sample is dissolved in an appropriate solvent, and the analyte is converted to an insoluble form of a known compound. The precipitate is then collected, dried and weighed. From this weight, the amount or percent of the analyte in the original sample can be determined.
