Polar and non-polar compounds and their solubility

AI Thread Summary
Naphthalene's solubility in liquid ammonia, despite its non-polar nature, raises questions due to ammonia's polar characteristics. The discussion highlights the unexpected solubility of naphthalene in liquid ammonia, which contradicts typical solubility rules. The inquiry stems from research focused on naphthalene carry-over in gas systems, where literature indicates that naphthalene can dissolve in liquid ammonia, prompting further exploration into the underlying chemical interactions or reactions that facilitate this solubility.

TL;DR Summary
Hydrocarbon Solubility in Polar solutions
Hi
Please can anyone explain why Naphthalene is soluble in liquid Ammonia when Naphthalene is Non-polar and Ammonia is Polar?
 
Chemistry news on Phys.org
Good question. I would expect the solubility to be very low. Where does your question come from? Is this related to some chemical reaction or rather spectroscopy?

Hi DrDu, thanks for your response.
The question comes from research into modes of Naphthalene carry-over in gas systems.
I was surprised when I was faced with articles stating Naphthalene to be soluble in Liquid Ammonia.
 

Thread 'Humidity of a saturated NaCl solution with anticaking additive'

I want to test a humidity sensor with one or more saturated salt solutions. The table salt that I have on hand contains one of two anticaking agents, calcium silicate or sodium aluminosilicate. Will the presence of either of these additives (or iodine for that matter) significantly affect the equilibrium humidity? I searched and all the how-to-do-it guides did not address this question. One research paper I found reported that at 1.5% w/w calcium silicate increased the deliquescent point by...

Thread 'Why does having 8 valence electrons make an element inert?'

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!!

Thread 'Resists for etching Aluminium with NaOH'

I'm trying to find a cheap DIY method to etch holes of various shapes through 0.3mm Aluminium sheet using 5-10% Sodium Hydroxide. The idea is to apply a resist to the Aluminium then selectively ablate it off using a diode laser cutter and then dissolve away the Aluminium using Sodium Hydroxide. By cheap I mean resists costing say £20 in small quantities. The Internet has suggested various resists to try including... Enamel paint (only survived seconds in the NaOH!) Acrylic paint (only...
