The determination of an element or species through the measurement of mass of a well-characterized insoluble product of a definite chemical reaction involving that element or species
Gravimetric Methods of Analysis
Based on mass measurements with an analytical balance
Yields highly accurate and precise data
Precipitation Gravimetry
The analyte is separated from a solution of the sample as a precipitate and is converted into a compound that can be weighed
Volatilization Gravimetry
1. Analyte separated from a solution by converting it to gas
2. The mass of the gas serves as a measure of the analyte concentration
Electrogavimetry
The analyte is separated by deposition of an electrode by an electric current
Gravimetric titrimetry
The mass of a reagent of known concentration required to react completely with analyte provides information needed to determine the analyte concentration
