Basic Analytical Chemistry (Introduction)

What is analytical chemistry?

• the area of chemistry responsible for characterizing the composition of matter on qualitatively measurement.

• the area of chemistry responsible for characterizing the composition of matter on qualitatively and quantitative measurement.

• the area of chemistry responsible for characterizing the composition of matter on quantitative measurement.

A qualitative test will reveal....

• identity of a material
• amount of a sample
• usefulness of a compound
• purity of a substance

..................... based on measurement of the interaction between electromagnetic radiation and analyte atoms or molecules.

• Chromatographic methods

• Spectroscopic methods

It is the study that involves how we analyze the chemical components of a sample
