Interpretation The reasons why methanol and ethanol are soluble in water whereas octanol is poorly soluble have to be determined.
Concept introduction:
‘Like dissolves like’ principle said that polar compounds including ionic compound should be more soluble in polar solvent. Likewise, non-polar compound should be more soluble in non-polar solvent. Other hand, compounds with similar intermolecular force capability to soluble in one another because solute-solvent interactions are similar signification to the solute-solute interaction.
‘ The set of repulsive and attractive force between molecules that result from the polarity between neighboring molecules is represented as intermolecular force. There are four types of intermolecular forces:
- Hydrogen bonding
- London dispersion force
- Ion – dipole force
- Dipole – Dipole force
Hydrogen bond: Hydrogen is bonded to strong electronegative atom like oxygen, nitrogen etc.

- If one mixes 50 cm3 of EtOH and 50 cm3 of H2O at room temperature; will the total volume of the solution will be 100.0 cm3? Justify your answer with appropriate calculations and explanations.arrow_forwardThe osmotic pressure of an aqueous solution of a certain protein was measured to determine the protein’s molar mass. The solution contained 3.50 mg of protein dissolved in sufficient water to form 5.00 mL of solution. The osmotic pressure of the solution at 25 °C was found to be 1.54 torr. Treating the protein as a nonelectrolyte (The Van't Hoff Factor = 1), calculate its molar mass.
