14 replies with yours that are still wrong - see my reply directly above! :rolleyes:
apart from spelling Le Chatelier wrong (no excuse - my stupid) are you implying there was anything incorrect with my post?
In regards to the above statement in your last post, the above statement is the reverse of what actually happens. In fairness though the above statement contradicts what you had stated in your preceeding sentence so I’m not sure if you were trying to describe the solubility of solids.
I’m wondering if anyone is able to answer my OP in operational, descriptive terminology, rather than than in technical terminology. When you talk about, say, vapor pressure, you are using a term that has specific meaning to you, but which does not actually describe what is really happening. Put another way, if you tell me that you know the name of a bird, all you know is what people call it - you don’t know anything about the bird. I’m trying to understand why a cold liquid, made of moving molecules, would hold more molecules of another material that normally exists as a gas at that temperature than it would at a higher temperature. Is it possible to simplify the answer without using language that implies an understanding of several other concepts?
I am afraid CC that the world sometimes cannot be explained in simpler concepts. All changes in the world are driven by two things: 1. heat output (enthalpy) and 2. entropy which is increasing disorder (slightly simplified but not going into that here). If you want to understand any changes such as boiling, dissolving, chemical reactions etc you gotta start there. Changes that give off heat generally become less favorable at higher temperatures - that is the case for gases dissolving and it cant be explained in terms of bouncing balls.
Waterman please read my link and you might get the concept that gases generally first become less soluble and *then more soluble * as the temperature rises - which cannot be explained entirely by Le Chateliers principle
