Discussion Overview

The discussion revolves around the solubility of acetanilide, specifically in petroleum ether and diethyl ether. Participants share their experimental observations and seek clarification on the solubility characteristics of acetanilide in these solvents.

Discussion Character

  • Exploratory, Experimental/applied, Debate/contested

Main Points Raised

  • One participant recalls their acetanilide sample being soluble in petroleum ether but notes conflicting information suggesting it may be insoluble.
  • Another participant confirms that acetanilide is soluble in diethyl ether but expresses uncertainty regarding its solubility in petroleum ether.
  • A different participant states that acetanilide is "very sparingly soluble" in petroleum ether.
  • One participant suggests that the small size of the acetanilide sample and the excess of petroleum ether could explain its complete dissolution in their experiment.
  • Another participant challenges this by proposing that the small sample size might have led to it being undetectable rather than truly dissolved.

Areas of Agreement / Disagreement

Participants express differing views on the solubility of acetanilide in petroleum ether, with some suggesting it is very sparingly soluble while others have conflicting experimental results. The discussion remains unresolved regarding the definitive solubility in petroleum ether.

Contextual Notes

Participants mention varying experimental conditions, such as sample size and solvent excess, which may influence the observed solubility. There is also a lack of consensus on the definitions of solubility in the context of different solvents.

Hey guys.

Really amateurish question but I just wanted to check something. I was doing an experiment a little while ago and from what I recall my acetanilide sample was soluble in petroleum ether but I just read somewhere that some other fellow got a result suggesting it is insoluble. So my question is is it soluble? I know it dissolved fairly happily in ether but I don't want to make any assumptions.

Petroleum ether or diethyl ether?

I know for certain that it is soluble in diethyl ether but uncertain for pet. ether.
 
Very sparingly soluble in pet ether.

Thanks.

When I did the test the sample was quite small and the pet ether in excess so that could explain why my sample dissolved in its entirety?
 
I don't think so. It's more likely that the sample was so small you lost sight of it.
