The Power of Carbon: 4 Carbon Bonds

AI Thread Summary
Carbon typically forms four bonds, but the possibility of a quadruple bond between two carbon atoms is largely theoretical. The C2 molecule is often cited as a candidate for such bonding, yet it is primarily characterized by double bonds. Recent discussions highlight that while some research suggests the existence of a carbon-carbon quadruple bond, it is considered weak and not a true bond in the traditional sense. The concept remains debated within the scientific community, with some experts acknowledging it as a theoretical possibility rather than a practical reality.

Can carbon form four bonds with another carbon?
 
Chemistry news on Phys.org
The only possibility for a quadruple bond between two carbon atoms would be the C2 molecule, as no other bonding to additional atoms would be possible. And C2 is only doubly bonded:

I wouldn't consider this "long-bond" a real bond as it is also much weaker than a true bond. But as it is only a concept you are of course free to do so.
 

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...
