Solutions Solutions The enthalpy change of solution is the quantity of heat produced or absorbed when a one mole of a substance is dissolved in a large volume of a solvent at constant pressure. ...more on Wikipedia about "Enthalpy change of solution"
Flory-Huggins solution theory is a mathematical model of the thermodynamics of polymer solutions which takes account of the great dissimilarity in molecular sizes in adapting the usual expression for the entropy of mixing. The result is an equation for the Gibbs free energy change for mixing a polymer with a solvent. Although it makes simplifying assumptions, it generates useful results for interpreting experiments. Paul Flory and Maurice Huggins were American physical chemists, and Flory received the Nobel Prize in Chemistry for this work in 1974. They developed the theory independently while Flory was working for Esso and Huggins was working for Kodak. ...more on Wikipedia about "Flory-Huggins solution theory"

A molar solution is one that contains one mole of solute per litre. ...more on Wikipedia about "Molar solution"
In biology percentage solutions are often preferred to molar ones. A 1% solution would have 1g of solute to 100ml of solvent. This would be labelled as a weight/ volume [w/v]percentage solution. For w/w then both solvent and solute would need to be weighed in the required ratios. Volume would accordingly be measured using a measuring cylinder, volumetric flask, pipette or similar. ...more on Wikipedia about "Percentage solution"
In chemistry, Raoult's law states that the vapor pressure of each component in an ideal solution is dependent on the vapor pressure of the individual component and the mole fraction of the component present in the solution. ...more on Wikipedia about "Raoult's law"

(Solubility) A substance is soluble in a fluid if it dissolves in that fluid. The dissolved substance is called the solute and the dissolving fluid (usually present in excess) is called the solvent, which together form a solution. The process of dissolving is called solvation, or hydration if the solvent is water. ...more on Wikipedia about "Solubility"
Solubility equilibrium is any chemical equilibrium between solid and dissolved states of a compound. ...more on Wikipedia about "Solubility equilibrium"
In chemistry, a solution is a homogeneous mixture of one or more substances (the solutes) dissolved in another substance (the solvent). A common example would be a solid dissolving into a liquid, like salt or sugar dissolving in water (or even gold into mercury, forming an amalgam); but also gases may dissolve into liquids, like carbon dioxide or oxygen in water, and liquids and gases into themselves. ...more on Wikipedia about "Solution"
Solvation is the attraction and association of molecules of a solvent with molecules or ions of a solute. As ions dissolve in a polar solvent they spread out and become surrounded by solvent molecules. The bigger the ion, the more solvent molecules are able to surround it and the more it becomes hydrated. Similarly, the higher the charge on the ion the more solvent molecules it attracts. Solvent molecules have the effect of pulling apart the electron clouds that surround an ion's nucleus, and the higher the charge and the smaller the ion (these factors combined are known as charge density) then the larger an ion becomes when dissolved. ...more on Wikipedia about "Solvation"
A solvent is a liquid that dissolves a solid, liquid, or gaseous solute, resulting in a solution. The most common solvent in everyday life is water. The term organic solvent refers to most other solvents that are organic compounds and contain carbon atoms. Solvents usually have a low boiling point and evaporate easily or can be removed by distillation, thereby leaving the dissolved substance behind. Solvents should therefore not react chemically with the dissolved compounds — they have to be inert. Solvents can also be used to extract soluble compounds from a mixture, the most common example is the brewing of coffee or tea with hot water. Solvents are usually clear and colorless liquids and most of them have a characteristic odor. The concentration of a solution is the amount of compound that is dissolved in a certain volume of solvent. The solubility is the maximal amount of compound that is soluble in a certain volume of solvent at a specified temperature. ...more on Wikipedia about "Solvent"
