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?

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 'How to make Sodium Chlorate by Electrolysis of salt water?'

I have a power supply for electrolysis of salt water brine, variable 3v to 6v up to 30 amps. Cathode is stainless steel, anode is carbon rods. Carbon rod surface area 42" sq. the Stainless steel cathode should be 21" sq. Salt is pure 100% salt dissolved into distilled water. I have been making saturated salt wrong. Today I learn saturated salt is, dissolve pure salt into 150°f water cool to 100°f pour into the 2 gallon brine tank. I find conflicting information about brine tank...

I tracks prices of Pt, Pd, Ru, Ir and Ru. Of the 5 metals, rhodium (Rh) is the most expensive. A year ago, Rh and Ir...
