Qualitative Analysis

Subject: Chemistry

Book: General Chemistry

Qualitative analysis identifies the chemical components in a sample without measuring exact amounts. Classic techniques include flame tests (e.g., sodium gives a yellow flame), precipitation reactions, and colorimetric changes. Modern methods like spectroscopy also provide qualitative insights. Qualitative analysis is fundamental in forensic investigations, material identification, and preliminary screening of unknown substances.
