Document Summary
To introduce proper technique in the performance of any titration analysis. To determine the molar concentration ( standardize ) a titrant solution against a primary standard. To determine the empirical formula of a compound composed of only two elements. Experience properly reading and recording volumetric measurements from volumetric glassware markings. Conceptual mastery of the inter- relationship between atomic and molecular mass, chemical formulae and concentration units. Basic understanding of determining the mole-to- mole relationship between acid and base which occur during neutralization. In the laboratory, the quantitative analysis of materials of unknown composition is an important application of stoichiometry. When the measurements used in the analysis involve volumes of solution and volumetric glassware--pipettes, burettes, volumetric flasks--the process is called volumetric analysis. Typically, an unknown sample is allowed to react to the exact point of completion with an accurately measured volume of a second reactant whose concentration is well- known (a standard solution and titrant).
