is a measurement science consisting of a set of powerful ideas and methods that are useful in all fields of science, engineering, and medicine.

reveals the identity of the elements and compounds in a sample.

Indicates the amount of each substance in a Sample..

are the components of samples that are determined.

unravel the mechanisms of chemical reactions through reaction rate studies

also play a vital role in many research areas in chemistry, biochemistry, biology, geology, physics, and the other sciences.

is often called the central science

its top-center position and the central position of analytical chemistry in the figure emphasize this importance.

determine the mass of the analyte or some compound chemically related to it.

measures the volume of a solution containing sufficient reagent to react completely with the analyte

measure electrical properties such as potential, current, resistance, and quantity of electrical charge

Explore the interaction between electromagnetic radiation and analyte atoms or molecules or the emission of radiation by analytes

The choice is sometimes difficult and requires experience as well as intuition.

is the process of determining how much of a given sample is the material by its indicated name.

is the process of collecting a small mass of a material whose composition accurately represents the bulk of the material being sampled.
