Determining what is present in a particular chemical sample is called chemical analysis. Chemical analysis can be qualitative or quantitative. Qualitative analysis involves determining what substances are present in a sample. Quantitative analysis determines how much of each substance is present in a sample. Two common methods of quantitative analysis are gravimetric analysis and volumetric analysis. Volumetric analysis is concerned with the measurement of solution volumes. Gravimetric analysis is a method of analysis that involves the measurement of masses. Gravimetric Analysis. This involves the accurate measurement of masses. This is often done in the pharmaceutical, food and mining industries. Often, procedures will involve the weighing of precipitates to find product mass, measurement of combustion by-products and in the study of empirical formulae. Percentage composition. The percentage composition of a chemical compound specifies the percentage by mass of each of the different elements present in the compound. For example, water consists of 11.1 per cent hydrogen and 88.9 per cent oxygen by mass. A 100 g sample of water therefore, contains 11.1 g of hydrogen and 88.9 g of oxygen. The percentage composition of a compound can be determined experimentally using gravimetric analysis. For example, information about chemical composition can be determined by decomposing the compound and weighing one or more of the products.
