AI Thread Summary
The solubility product for water is 10^-14, indicating the equilibrium between hydronium ions and hydroxide ions. In the case of acetic acid, it undergoes self-ionization to form HHOAC(+) and OAC(-). However, this process is characterized by a dissociation constant rather than a solubility product. Many acids, including sulfuric acid (H2SO4), exhibit similar self-ionization behavior. Understanding the distinction between solubility products and dissociation constants is crucial in acid-base chemistry.

TL;DR Summary
can pure acetic acid donate a proton to itself the same as pure water donates a proton to itself to form hydronium ion?
The solubility product for water is 10 to the minus fourteenth power.(water forming hydronium ion and its complement). What is the solubility product of pure acetic acid forming HHOAC(+) and OAC(-) ?

Yes. Google “acetic acid self-ionization.”
 
Many acids do the same, including H2SO4.
 
That's not a solubility product, it's a dissociation constant.

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...
