Questions tagged [solutions]
This tag should be applied to questions dealing with solutions of any kind. A solution is a liquid or solid phase containing more than one substance where, for convenience, one (or more) substance(s) called the solvent is treated differently from the other substances, which are called solutes. If water is the solvent, then the more appropriate 'aqueous-solution' tag should (also) be specified.

Why does entropy increase on mixing two ideal liquids?
Why does entropy increase when we mix two ideal liquids? In my opinion entropy shouldn't change.
Say we have two beakers of equal volume filled with $\ce{H2O(l)}$. I mark them red and blue (the ...

Does osmotic pressure depend on the quantities of the outer membrane solvent?
$$\pi V = nRT$$
What is the osmotic pressure at $\pu{25^oC}$ of an aqueous solution of 0.0010 M $\ce{C12H22O11}$ (sucrose)?
We just need to substitute the data into equation (13.4)
$$\pi = \frac{\pu{...

Considering Le Chatelier's principle, what happens when you add more solute to a saturated solution already in equilibrium?
If I'm not wrong saturated solutions are in dynamic equilibrium. Will the addition of solute disturb the equilibrium? What exactly occurs and how to apply Le Chatelier's principle?

Vapor Pressure of Two Immiscible Liquids [duplicate]
The vapor pressure of two immiscible liquids (A and B) is the sum of their vapor pressures in their pure liquid form.
Intuitively, I don't see how this is possible. If the liquids are being stirred ...
