Is condensation reversible above critical pressure?

AI Thread Summary
A 50% carbon dioxide and 50% nitrogen gas mix at 1800 psig and 70°F raises questions about the dewpoint of CO2 in the mixture. The dewpoint is crucial for understanding when CO2 will condense as temperatures drop. Reference sources for the dewpoint can include thermodynamic tables or software that provides phase behavior data for gas mixtures. If the temperature falls below the dewpoint and CO2 condenses, raising the temperature should allow the CO2 to return to the gas phase, re-establishing the original mix. The inquiry is valid and highlights important considerations in gas mixture behavior under varying temperature and pressure conditions.

I have a 50% carbon dioxide and 50% nitrogen gas mix at 1800psig, 70*F. Is there a reference source for the dewpoint of the CO2 in that mix?

Assuming the temperature falls below that dewpoint and the CO2 condenses, will it return to a mix as the temperature is raised?

thanks, kw

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...
