PH — is the measure of the acidity or alkalinity of a solution. It is formally a measure of the activity of dissolved hydrogen ions (H+), but for very dilute solutions, the molarity (molar concentration) of H+ may be used as a substitute with little… … Wikipedia
Molality — In chemistry, the molality, b (or m), of a solvent/solute combination is defined as the amount of solute, nsolute, divided by the mass of the solvent, msolvent (not the mass of the solution)[1]: If a mixture contains more than one solute or… … Wikipedia
Activity (chemistry) — In chemical thermodynamics, activity (symbol a) is a measure of the “effective concentration” of a species in a mixture, meaning that the species chemical potential depends on the activity of a real solution in the same way that it would depend… … Wikipedia

Boiling-point elevation — describes the phenomenon that the boiling point of a liquid (a solvent) will be higher when another compound is added, meaning that a solution has a higher boiling point than a pure solvent. This happens whenever a non volatile solute, such as a… … Wikipedia
Davies equation — The Davies equation is an empirical extension of Debye–Hückel theory which can be used to calculate activity coefficients of electrolyte solutions at relatively high concentrations. The equation, originally published in 1938,[1] was refined by… … Wikipedia
