Expert Solution

Step 1

Negative controls are used to establish a baseline or reference point for comparison with other samples in the experiment. In the case of distilled water, it is used to establish the absence of any effect or change that may occur due to factors other than the variable being tested.

For example, if you are conducting an experiment to test the effect of a new chemical on plant growth, you may use distilled water as a negative control to ensure that any observed effects on plant growth are due to the chemical being tested and not to any contaminants or substances present in the water used for the experiment.
