Gravimetric analysis involves separating the analyte from the sample by a physical or chemical process, determining its mass, and then calculating its concentration in the sample based on the stoichiometry of the relevant process. A large number of important reactions are included in three categories: precipitation, acid-base, and oxidation-reduction (redox). Combustion analysis is a gravimetric method used to determine the elemental composition of a compound by collecting and weighing the gaseous products of its combustion. The substances that make up a(n) are not bonded together, so adding more of one substance in a solution will not change the composition of the solution. or more substances, called reactants , are transformed into ab`q]%P#\ djPK:z5zF!5K8( Now have the class read the 'What Is Matter . <> 3.
