Final answer:
Gravimetric analysis is a quantitative chemical analysis method that involves the separation of an analyte from a sample by a physical or chemical process and subsequent mass measurements of the analyte. Two common examples of gravimetric analysis are precipitation and filtration.
Step-by-step explanation:
Gravimetric analysis is a quantitative chemical analysis method that involves the separation of an analyte from a sample by a physical or chemical process and subsequent mass measurements of the analyte. Two common examples of gravimetric analysis are precipitation and filtration. In precipitation, a reactant is added to the sample to form a precipitate, which is then isolated by filtration, dried, and weighed. The mass of the precipitate is then used to calculate the concentration of the analyte.
