Final answer:
An experiment is a controlled scientific investigation performed in a laboratory to test hypotheses, explain observations, and verify results in chemistry.
Step-by-step explanation:
An experiment is a special type of scientific investigation that is performed under controlled conditions, usually in a laboratory. It generally tests how one variable is affected by another. Chemistry is a science based on observation and experimentation, where knowledge is based on reproducible experiments that can verify results.
For example, if you want to test the purity of a chemical, you can design an experiment to analyze it and compare the results with the manufacturer's claim. This analysis is considered an experiment because it involves testing a hypothesis and using procedures accepted by the scientific community.
So, in summary, experiments in chemistry involve controlled investigations performed in a laboratory to test hypotheses, explain observations, and verify results.
