When a molecule is dissolved in a solvent like water, a solution is created. The molecule now has the possibility to interact with the solvent using the available intermolecular forces (IMF). The golden rule of solubility is “like dissolves like” meaning polar molecules dissolve in polar solvents and nonpolar molecule dissolve in nonpolar solvents. The available IMF for a solution increase since there is also the possibility of forming an even stronger ion-dipole interaction between an ionic salt and a polar solvent. Water is the most polar solvent, but there are also polar organic solvents like the ketone acetone, CH3COCH3. The least polar solvents are alkanes since they are nonpolar functional groups. Which functional group: alkane, ketone, or alcohol is likely to be the least soluble in water? What IMF exists between the functional group and the polar solvent water? Which functional group: alkane, ketone, or alcohol is likely to be the most soluble in water? What IMF exists…

The freezing point of a liquid will change when a solute is added. Explain how the addition of salt impacts the boiling point of water. Calculate the freezing point change for a given concentration. a) What is the strongest intermolecular force between two molecules of water in ice? b) When an electrolyte solution (such as NaCl) is added to ice, the ions have with water _the ability of the water molecules to form a solid ice structure. molecules and thus, c) Given that water's freezing point is 0.00°C and the freezing point depression constant (Kf) is 1.86 °C·kg/mol, calculate the freezing point depression for a 3.30 molal solution (moles/kg) of NaCl in water. Assume ideal behavior of the ions. d) CaCl, is often used to melt ice on sidewalks. Calcium chloride is more effective at melting ice than NaCl. Choose the best explanation for this observation.
