Final answer:
Gravimetric analysis is used to determine analyte concentrations by inducing a state change and weighing the substance before and after treatment, with everyday examples including moisture content determination in food and combustion analysis for elemental composition.
Step-by-step explanation:
Gravimetric analysis is a quantitative chemical analysis method used for determining the concentration of an analyte in a sample. This method involves separating the analyte from the rest of the sample through a physical or chemical process, which often induces a change in the state of the analyte.
A typical example of gravimetric analysis in everyday life is the determination of moisture content in food products. By weighing the food before and after a controlled heating process that evaporates water, the moisture content can be calculated. Another common application is in combustion analysis, where the elemental composition of a compound is determined by combusting the substance and weighing the gaseous products produced.
