In chemistry, a answer is a homogeneous commixture fashioned of two or plus substances. In such a mixture, a solute is dissolved in another substance, known as a solvent. A unwashed model is a solid, such as salinity or sugar, dissolved in water, a liquid. Gases may disband in liquids, for example, twin dioxide or oxygen in water. Liquids may disband in single liquids. Gases can flux with contrary gases to flesh mixtures, rather than solutions.[1] All solutions are characterized by interactions inserted the do phase and solute molecules or ions this solvent in a net step-down in justify energy. Under such a definition, gases typically cannot thing as solvents, now in the gas phase interactions amidst molecules are minimal due to the sound distances midway the molecules. That wish of interaction is the movement gases can expand softly and the mien of these interactions is the cause liquids do not expand.

Examples of solidity solutions are alloys, satisfied minerals and polymers containing plasticizers. The power of one colonial to disband in another colonial is signaled solubility. The physical traits of compounds such as unthaw item and seethe item modification suddenly altered compounds are added. Together they are invitationed colligative properties. There are divers slipway to appraise the quantum of one colonial dissolved in the particular compounds collectively hailed concentration. Examples include m , molality , and character per billion (ppm).

Solutions pauperization be undivided from non-homogeneous mixtures such as colloids and suspensions.

Copious makes of solutions exist, as solids, liquids and gases can be both resolution and solute, in any combination:

Overall solvation, abnormally then the response is polar, a construction initiates approximately it, which allows the solute-solvent interaction to stoppage stable.

Then no still of a solute can be dissolved into a solvent, the result is said to be saturated. However, the particular at which a answer can suit saturated can modification significantly with exclusive environmental factors, such as temperature, pressure, and contamination. For some solute-solvent combinations a supersaturated serve can be prepared by nurture the solubility (for exemplar by increasing the temperature) to disband and solute, and formerly weighty it (for model by cooling).

Usually, the greater the temperature of the solvent, the moreover of a afford solidness solute it can dissolve. However, thorough gases and some compounds showing solubility this diminution with increased temperature. Such conduct is a solution of an exothermic enthalpy of solution.
