The best approach for Greg and Susan would be option C: ask the teacher to dispose of both samples and obtain new samples with labels. This ensures safety and prevents any potential risks from incorrectly identifying the liquids. It's critical in a laboratory setting to know exactly what substances are being used, especially if they could be hazardous or reactive. Guesses or tests that involve tasting or smelling could also pose risks, so it's important to rely on proper labeling and identification procedures.
Greg and Susan are conducting an experiment. Each has a clear liquid which they pour into a test tube and place in a test tube rack. After setting up the rest of the lab equipment, they realize they don't know which liquid is which. How should they proceed? A guess which liquid is which and label them B taste and small each liquid to identify them and label C ask the teacher to dispose of both samples and obtain new samples with labels D continue the experiment and try to identify the substances from the results
