Question

Provide two other common examples of gravimetric analysis.

a) Titration and chromatography
b) Spectrophotometry and NMR
c) Precipitation and filtration
d) Centrifugation and distillation

Answer 1

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.
