Study Notes
Analytical Chemistry
- The main focus of analytical chemistry is to identify and quantify the chemical composition of substances.
Qualitative Analysis
- Qualitative analysis in analytical chemistry aims to identify the presence or absence of a particular substance or ion in a sample.
Classical Qualitative Methods
- In classical qualitative methods, identification is often based on the physical properties of the substance, such as color, odor, and melting point.
- Other common basis for identification in classical qualitative methods include precipitation reactions, solubility, and flame tests.
Instrumental Methods
- Instrumental methods in analytical chemistry primarily focus on the measurement of physical properties, such as spectra, chromatograms, and electrochemical responses.
Qualitative vs. Quantitative Analysis
- The main difference between qualitative and quantitative analysis in analytical chemistry is that qualitative analysis determines the presence or absence of a substance, while quantitative analysis determines the exact amount or concentration of the substance.
