Gravimetric calculations and solutions
WebGravimetric analysis or gravimetry refers to the quantitative determination of a chemical constituent using mass or weight measurements. The unknown chemical constituent (A) to be determined is converted into a substance of known composition (AB) by carrying out a chemical reaction. WebWhich of the following statements is important when assessing a gravimetric analysis? The desired substance must be completely precipitated. The stoichiometric relationship between the analyte and the precipitate must be known. The precipitate should be of low solubility so that losses associated with dissolution of the precipitate are minimal.
