Chem people- "soluable" and "miscible", please explain?

Question

I read something that said one kind of alcohol (ethyl) was "soluable" in water. It went on to say another type of alcohol (isopropyl) is "miscible" in water, and therefore would not seperate into layers if mixed with water. I'm thinking "soluablility" technically occurs when intermolecular bonds that exist when the substance is by itself, get broken. This allows it to be dissolved. So, what's "miscible"? "Sort of soluable"? If there is a real difference, please explain.

Answer 1

Actually both ethyl alcohol and isopropyl alcohol are totally miscible. A substances solubility varies in water. Substances (polar liquids) that are miscible are completely soluble in water. Miscible means soluble in all proportions so no matter how much solute it will dissolve in water.

Most substances (like inoganic salts and some polar organics) are slightly soluble which means that only some of the substance can dissolve and there is a point in which the solution is saturated. When a solution is saturated with a solute it can no longer dissolve that solute. Now there are some substances (like non-polar substances) that don't dissolve at all no matter how much water is present.
