AI Thread Summary
The discussion focuses on the dissociation of acids in aqueous solutions, emphasizing that stronger acids fully dissociate while weak acids only partially dissociate. It clarifies that the dissociation process involves the hydrogen cation (proton) from the acid reacting with water to form hydronium ions (H3O+), rather than simply binding to hydrogen in water. The conversation also highlights that not all substances containing hydrogen are acidic, as acidity depends on various factors beyond the presence of hydrogen. The transformation of water into hydronium ions is noted as a significant change, indicating that H2O is no longer in its original form once it gains a positive charge.

For example, the stronger an acid the more the Ions disassociate in an aqueous solution, right?
If I have the idea right, an acid disassociates in water B/C of the reason it has Hydrogen in it (this is part of the reason) the Hyrdrogen atom in the acid separates from the other atom(s) it was attached to and binds with the H atom in the aqueous solution?

This is so hard...

It is not hard, you are just trying to run before you know how to crawl.

As a first approximation, there are strong acids - 100% dissociated in water - and weak acid, dissociated only partially. Let's not try to discuss why's for now, as they are combination of many factors.

If anything, hydrogen (more precisely - hydrogen cation, or just a proton) from acid dissociation reacts with water molecule, creating hydronium ion (cation) H3O+. It doesn't bind to hydrogen in water molecule, more like oxygen. And acids don't dissociate just because they have hydrogen in molecule - there is plenty of substances that have hydrogen in molecules and they are not acidic.

So the cation is attracted to the H20 atom, so now that H20 has a +1 charge it is known as Hydronium (H30+)?
 
Yes. Just note you can't say

It is no longer H2O that has a +1 charge, it was converted to something completely different.
 
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...
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!!
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...
