Document Summary

Solution consists of a solvent and one or more solutes. Saturated solution- maximum amount of a solute that will dissolve in a certain temperature. Solubility- the amount of solute dissolved in a given volume of a saturated solution. Unsaturated solution- a solution that contains less solute than it has the capacity to dissolve. Supersaturated solution- contains more dissolved solute than is present in saturated solution (crystallization) 13. 2- a molecular view of the solution process: Solvation: when molecules of the solute disperse and are separated from one another and then are surrounded by solvent molecules. The ease of solvation is determined by the strengths of: Such interactions exist in a mixture of different substances. Solutions can have the following additional intermolecular forces: Ion-dipole: the charge of the ion is attracted to the partial charge on a polar molecule. Dipole-induced dipole: the partial charge on a polar molecule induces a temporary partial charge on a neighboring nonpolar molecule or atom.

Can you please, paraphrase this sentences for me (type the answer please

(In a sugar crystal, the sucrose molecules are arranged in a repeating pattern that extends in all three dimensions, and all of these molecules are attracted to each other by intermolecular forcesâa type of interaction that binds molecules together and is weaker than the bonds between atoms in a molecule.(Tom Husband,October 2014)

When you add granulated sugar to water, some of the sucrose molecules start separating from one another because they are attracted to the water molecules (Fig. 3). When water and sucrose molecules are close to each other, they interact through intermolecular forces that are similar to the intermolecular forces between sucrose molecules.

The dissolving process involves two steps: First, the water molecules bind to the sucrose molecules; and second, the water molecules pull the sucrose molecules away from the crystal and into the solution.

In general, only a certain amount of a solid can be dissolved in water at a given volume and temperature. If we add more than that amount, no more of that solid will dissolve. At this stage, we say that the solution is saturated. The additional solid just falls to the bottom of the container.
