You can observe a colorless gas indirectly through its effects or reactions. For instance, you might notice changes in the environment, such as the formation of bubbles, changes in temperature, or a shift in pH when the gas interacts with other substances. Additionally, using specific detectors, sensors, or chemical indicators can help visualize the presence of the gas. Examples include using litmus paper to detect carbon dioxide or a flame test for hydrogen.
