To verify if the collected substance is turpentine, a laboratory experiment should focus on analyzing its chemical composition, as turpentine is a complex mixture rather than a single compound. Key properties to examine include the presence of alpha-pinene, which constitutes 70 to 80% of turpentine oil. Techniques such as gas chromatography could be employed to identify and quantify the components. Additionally, transforming alpha-pinene into terpineol, which has a distinct lilac odor, could serve as an indirect confirmation of the presence of turpentine. Understanding the classification criteria for turpentine may also aid in the verification process.
