    Study Notes

    Gravimetric Analysis

    • In precipitation gravimetry, the signal is the mass of the precipitate formed.

    Types of Gravimetric Analysis

    • Particulate gravimetry involves determining the mass of a particulate analyte following its separation from its matrix.

    Chemical Reaction in Gravimetric Analysis

    • The reaction aA + rR → AaRrpt represents a chemical reaction in gravimetric analysis, where a and r are stoichiometric coefficients, A is the analyte, and R is the reagent.

    Volatilization Gravimetry

    • Volatilization gravimetry measures the mass of the residue remaining after a substance is heated to remove a volatile component.

    General Method of Gravimetry

    • Gravimetry is a general method based on the measurement of the mass of an analyte or a compound containing the analyte.
