Quantitative Analysis in Chemistry
Quantitative analysis in chemistry refers to the determination of the absolute or relative abundance of one or more particular substances present in a sample. It involves the measurement of the amount or concentration of an analyte, expressed as a numerical value in appropriate units). This branch of chemistry is crucial for calculating known quantities of materials and determining the amount of a chemical in a sample.
Quantitative chemical analysis employs various methods, which can be broadly classified as chemical or physical, depending on the properties utilized. Chemical methods rely on reactions such as precipitation, neutralization, and oxidation, while physical methods involve the measurement of physical properties such as density, refractive index, and electromagnetic force.
The basic tool in all quantitative analyses is the analytical balance, used for the accurate weighing of samples and precipitates. Some common techniques used in quantitative analysis include acid-base titration, gravimetric analysis, and combustion analysis/Text/4%3A_Stoichiometry%3A_Quantitative_Information_about_Chemical_Reactions/4.4%3A_Chemical_Equations_and_Quantitative_Analysis). These methods are essential for determining the quantity of a given component present in a sample.
