Dilution (equation) - Wikipedia
Dilution (equation) Diluting a solution by adding more solvent Dilution is the process of decreasing the concentration of a solute in a solution, usually simply by mixing with more solvent like adding more water to the solution To dilute a solution means to add more solvent without the addition of more solute
Solubility - Wikipedia
The solubility of a specific solute in a specific solvent is generally expressed as the concentration of a saturated solution of the two [1] Any of the several ways of expressing concentration of solutions can be used, such as the mass, volume, or amount in moles of the solute for a specific mass, volume, or mole amount of the solvent or of the solution
Volume fraction - Wikipedia
Volume percent is the concentration of a certain solute, measured by volume, in a solution It has as a denominator the volume of the mixture itself, as usual for expressions of concentration, [2] rather than the total of all the individual components’ volumes prior to mixing: volume percent = volume of solute volume of solution × 100 % = volume concentration × 100 % {\displaystyle
Boiling-point elevation - Wikipedia
The result is that in dilute ideal solutions, the extent of boiling-point elevation is directly proportional to the molal concentration (amount of substance per mass) of the solution according to the equation: [2] ΔTb = Kb · bc where the boiling point elevation, is defined as Tb (solution) − Tb (pure solvent)
Partition coefficient - Wikipedia
In the physical sciences, a partition coefficient (P) or distribution coefficient (D) is the ratio of concentrations of a compound in a mixture of two immiscible solvents at equilibrium This ratio is therefore a comparison of the solubilities of the solute in these two liquids The partition coefficient generally refers to the concentration ratio of un-ionized species of compound, whereas the
Molar concentration - Wikipedia
Molar concentration (also called amount-of-substance concentration or molarity) is the number of moles of solute per liter of solution [1] Specifically, It is a measure of the concentration of a chemical species, in particular, of a solute in a solution, in terms of amount of substance per unit volume of solution
Ionic strength - Wikipedia
The ionic strength of a solution is a measure of the concentration of ions in that solution Ionic compounds, when dissolved in water, dissociate into ions The total electrolyte concentration in solution will affect important properties such as the dissociation constant or the solubility of different salts
