Question
Chapter 6, Problem 6.59P
Interpretation Introduction
Interpretation:
The dissolution of ethanol in water should be explained.
Concept Introduction:
According to the fact in solutions, “like dissolves like”, polar solutes are soluble in polar solvents and non-polar solutes are dissolved in non-polar solvent. Ionic compounds are much more soluble in water than in organic materials.

- 6-111 As noted in Section 6-8C, the amount of external pressure that must be applied to a more concentrated solution to stop the passage of solvent molecules across a semipermeable membrane is known as the osmotic pressure The osmotic pressure obeys a law similar in form to the ideal gas law (discussed in Section 5-4), where Substituting for pressure and solving for osmotic pressures gives the following equation: RT MRT, where M is the concentration or molarity of the solution. (a) Determine the osmotic pressure at 25°C of a 0.0020 M sucrose (C12H22O11) solution. (b) Seawater contains 3.4 g of salts for every liter of solution.
