Analytical chemistry is a branch of chemistry focused on the qualitative and quantitative analysis of substances to understand their composition, structure, and properties. It involves a variety of techniques and methods to separate, identify, and quantify matter. Key aspects of analytical chemistry include: 1. **Qualitative Analysis**: Determining what substances are present in a sample. This involves identifying the chemical components or compounds without necessarily measuring their concentrations.
