AI Thread Summary
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.

Hi, after boiling some pine needles in about 200mL water and using a distillation device I believe, but can't be sure, that some turpentine was collected. What might be a laboratory experiment that could verify that in fact the substance is turpentine?

Check if those using turpentine don't have a definition what classifies as a turpentine. Turpentine is not a simple compound, rather a mixture, so there is no simple experiment, I expect some set of properties that have to be meet.
 
Turpentine oil contains mostly (70 to 80%) alpha-pinene. It is relatively easy to transform it into terpineol which has a nice lilac odor.
 
It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...
I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
