Dissolution is the dissociation or intermolecular occupation of a solute species in a solvent species to form a solution. A common dissolution process is the introduction of table salt crystals to water to form a saline water solution.Know More
A general rule of dissolution is that "like dissolves like." Substances must possess similar intermolecular forces for them to be able to dissolve in one another. Introducing a solute to a solvent must involve some interaction between the two species for a solution to form.
For a solid solute dissolving in a liquid solvent, the interactions between the molecules of the solute and the solvent must be stronger than the interactions in between the solvent molecules. The stronger these interactions are, the faster the solute dissolves in the solvent and the larger the amount of solute that the same amount of solvent is able to dissolve.
An example is the dissolution of strongly ionic salts in polar solvents, such as water. Water molecules are able to separate the solute molecules into individual ions and surround them to form a solution. This mechanism of surrounding the solute molecules with solvent molecules is called solvation and must occur regardless of the phases involved for a solution to form.Learn more about Solutions & Mixtures
Water temperature affects the rate at which sugar dissolves. Sugar dissolves faster in warmer water than it does in cooler water. Two things are required for a substance to dissolve and create a solution: the substance itself, or the solute, and the substance it is dissolving into, or the solvent.Full Answer >
Sugar dissolving in water is a physical change and not a chemical one. Chemical changes only occur when new substances form. Dissolving sugar in water does not cause a chemical reaction to take place.Full Answer >
A nonpolar solute is a substance that has no dipole elements and is dissolved in a solution. Many of these solutes are organic chemicals dissolved in organic liquids. Solutions follow the rule of like dissolves like, so nonpolar solutes are difficult to dissolve in polar solvents, such as water.Full Answer >
A solution's mass-mass percent concentration is given as the mass of the solute divided by the mass of the solution, which is then multiplied by 100 percent. The mass of the solution is equal to the mass of the solvent added to the mass of the solute.Full Answer >
