A qualitative test helps to identify the presence or absence of a substance in a sample. It provides information about the type or characteristics of the substance being tested for, rather than quantitative measurements like the amount present. Additionally, qualitative tests are often used as a preliminary step in analysis to guide further testing or confirmation.
