This approach is essential where a volatile species is released. Thermogravimetry is used to monitor sample mass changes with temperature, aiding in identifying decomposition reactions. Equipment ranges from simple crucibles to complex setups for trapping volatile products.

Calibrating involves adjusting the measured signal, Stotal, to match a known standard signal, Sstd. For example, balances are calibrated using reference weights, while spectrophotometers are checked by measuring absorbance of specific solutions.

In this section we develop a common vocabulary that we can use in later chapters.

It emphasizes using base SI units for measurements like mass and includes significant digits to maintain measurement precision. Concentrations are expressed in various ways, such as molarity and weight percent. Stoichiometric calculations are highlighted for quantitative analyses. Familiarity with lab equipment like balances and pipets is essential, as is the preparation of stock and dilute solutions.
