    Gravimetric Analysis of SULFATE as Barium Sulfate. Objectives * To learn the techniques associated with gravimetric analysis. * To use stoichiometry to calculate the percentage by mass of sulfate in an unknown sulfate salt. Background Gravimetric analysis is a quantitative method for accurately determining the amount of a substance by selective precipitation of the substance from an aqueous solution. The precipitate is separated from the remaining aqueous solution by filtration and

    Gravimetric analysis‚ by definition‚ includes all methods of analysis in which the final stage of the analysis involves weighing. In the most basic case‚ this could involve simply heating a sample to dryness and weighing to determine the amount of volatile components. In this account‚ however‚ shall limit to gravimetric methods which rely on the use of precipitation reactions. The quantitative determination of a substance by precipitation followed by isolation and weighing of the precipitate is

    Gravimetric Analysis Report Aim: Determine the % by mass composition of a sand-salt mixture. Background: Gravimetric analysis is a method which is based on the isolation of the desired sample in pure forms or in some combined form from a sample‚ and weighing the isolated constituent. Then from the weights of the sample or precipitate‚ a percentage can be calculated out of the constituent. Solubility is the amount of a substance which is called the solute‚ dissolves in a volume of liquid substance
