Determine whether each scenario is an example of a qualitative analysis or a quantitative analysis. a scientist analyzes a sample of ground water to determine which heavy metals have contaminated the source.

This is an example of a qualitative analysis.

Explanation:

Qualitative analysis is used to determine which types of things are present in a system.

Quantitative analysis is used to determine how much of those things are present in a system.

In this case, the scientist is only investigating which metals are in te water, not how much.

Qualitative Analysis

Explanation:

Qualitative Analysis is the experimental procedure for identifying elements or constituents in a chemical sample.

Quantitative has to do with in what amount or quantity these quantity exists. It aslo deals with the amoiunt that is needed for an acid to react with base and they reach an end point.

haven defined the above, it is okay to conclude that

A scientist analyzes a sample of ground water to determine which heavy metals have contaminated the source. is an example of Qualitative Analysis
