Practice: Indicate the most important type of intermolecular attraction responsible for solvation in the following solution:
Methanol, CH3OH, dissolved in ethanol, CH3CH2OH
Solutions are homogeneous mixtures that result from the dissolving of a solute by a solvent.
Concept #1: Solubility and Solutions
Recall, Solubility is a chemical property that deals with ability of a solute to dissolve in a solvent.
Example #1: The following table represents the solubilities of a few nonpolar gases in water at 25 ºC under a total pressure of 1.0 atm. Based on the information provided what is the most likely solubility value of F2?
Concept #2: Theory of Likes Dissolve Likes
In the Theory of Likes Dissolve Likes the solvent can only completely dissolve the solute if they share same Intermolecular Forces and/or Polarity.
Example #2: Identify the intermolecular forces present in both the solute and solvent, and predict whether a solution will form between the two: 50 g AsCl5 placed into 250 g H2O.
Practice: Indicate the most important type of intermolecular attraction responsible for solvation in the following solution:
Methanol, CH3OH, dissolved in ethanol, CH3CH2OH
Practice: Which of the following solutes will most readily dissolve in H2O?
Practice: Two pure chemical substance are likely to mix and form a solution if:
Practice: Which of the following statements is/are true?
I. The hydrocarbon methane (CH4) will dissolve completely in acetone (CH3COCH3).
II. Ammonia (NH3) will form a heterogeneous mixture with carbon tetrachloride (CCl4).
III. Pentane (C5H12) will form a homogeneous mixture with carbon tetrabromide (CBr4).
IV. Methanethiol (CH3SH) is miscible in fluoromethane (CH3F).
