LAB REPORT The action of heat on a solid hydrogencarbonate Aim To determine the effectiveness of gravimetric and volumetric analysis by testing the action of heat on solid hydrogencarbonate Hypothesis In this experiment, solid A, which is a hydrogencarbonate, has two experiments performed on it: one is a gravimetric analysis while another is a volumetric analysis, and the accuracy of each of the experiments. Gravimetric analysis is defined as a quantitative chemical analysis done by weighing a sample of purified precipitate1. Volumetric analysis is a quantitative analysis using accurately measured titrated volumes of standard chemical solutions2. In the first part of the experiment in gravimetric analysis, the solid hydrogencarbonate is heated. The following reaction occurs: Hydrogen gas is given off and the solid hydrogencarbonate loses mass to form a carbonate. By finding the number of moles of HCO3- and CO32-, it is possible to find the ratio of the moles given, which should be roughly about 2...
