Qualitative tests

Qualitative tests help to identify the presence (or absence) of an ion or compound in solution (or in air). A colour change is observed if the concentration of the ion or compound is above a specific minimum detection limit. There are no numerical amounts associated with these tests as usually they are “yes/no.”

Which is an example of qualitative test?

Qualitative analysis involves chemical tests, such as the Kastle-Meyer test for blood or the iodine test for starch. Another common qualitative test, used in inorganic chemical analysis, is the flame test.

What is a quantitative test?

A quantitative test tells you how much (the quantity) of an analyte is present. After the presence of an analyte has been established (which may involve a second, confirmatory test), the amount of the analyte present in the sample then may be measured.

What are qualitative and quantitative tests?

Quantitative research is designed to gather data points in measurable, numerical form. Qualitative research relies on the observation and collection of non-numerical insights such as opinions and motivations.
