This is concerning Le Chatelier's Principle and Equilbrium...
After I give a definition of what it means when it is said that salt is soluble and what is meant by insoluble, I am asked:
Why are these terms very broad and not very accurate?
Can someone start me on this... thanks.
fun stuff, chemistry. lol. Can't remember what Le Chatelier's Principle and Equilbrium is, but I would think it would be because you need to not only give the terms "soluble" and "insoluble" but tell why salt is soluble. Explain how the salt particles combine and attach themselves to the water particles, therefore breaking apart from the salt structure. Just saying something is soluble doesn't give alot of information, even if you give the defintion. Remember, in chemistry there are always reasons and (especially on tests and experiments) you are always better off explaining why things are the way they are.
Since this is not my area of expertise, I searched Google under the key words "Le Chatelier's Principle" to get these possible sources:

I hope this helps a little more. Thanks for asking.
I think it means just what it says. Soluble may tell a little but it doesn't say HOW soluble. Is it 1 mg/L or 100 mg/L or 50 g/L? Same thing with insolubility. Just where do you draw the line between something that is soluble and something that is insoluble?
