What is the purpose of chemical test kits in relation to lead?

To analyze soil composition
To show a color change upon contact with lead
To measure lead exposure in the air
To provide exact measurements of lead concentration

The correct answer is: To show a color change upon contact with lead

Chemical test kits are specifically designed to show a color change upon contact with lead. This reaction indicates the presence of lead, making these kits a useful initial screening tool for identifying lead contamination in various materials, such as paint, dust, or surfaces. The colorimetric response allows users to quickly gauge whether lead is present without needing to send samples to a laboratory. While the other options mention relevant activities, they do not accurately capture the primary function of these test kits. For instance, analyzing soil composition generally involves more comprehensive testing that examines various soil components and contaminants. Measuring lead exposure in the air requires specialized equipment and methodologies that go beyond the capabilities of basic chemical test kits. Providing exact measurements of lead concentration is also not within the scope of these kits, as they typically offer qualitative results (presence or absence of lead) rather than quantitative data.
