In aqueous solution BaCl 2 behaves as a simple salt; in water it is a 1:2 electrolyte [clarification needed] and the solution exhibits a neutral pH. Its solutions react with sulfate ion to produce a thick white solid precipitate of barium sulfate. BaCl 2 + Na 2 SO 4 → 2 NaCl + BaSO 4
In chemistry, a strong electrolyte is a solute that completely, or almost completely, ionizes or dissociates in a solution. These ions are good conductors of electric current in the solution. Originally, a "strong electrolyte" was defined as a chemical compound that, when in aqueous solution , is a good conductor of electricity.
K is the Kohlrausch coefficient, which depends mainly on the stoichiometry of the specific salt in solution, α is the dissociation degree even for strong concentrated electrolytes, f λ is the lambda factor for concentrated solutions. This law is valid for low electrolyte concentrations only; it fits into the Debye–Hückel–Onsager equation ...
Typical weak electrolytes are weak acids and weak bases. The concentration of ions in a solution of a weak electrolyte is less than the concentration of the electrolyte itself. For acids and bases the concentrations can be calculated when the value or values of the acid dissociation constant are known.
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. One of the main characteristics of a ...
To properly fulfil its functions, a supporting electrolyte must meet the following criteria: It must be completely dissociated in aqueous solution, so it is a strong electrolyte with a good conductivity; It must be sufficiently soluble in order to be able to increase the ionic strength of the solution in the experimental conditions to be explored;

An electrolyte in a solution may be described as "concentrated" if it has a high concentration of ions, or "dilute" if it has a low concentration. If a high proportion of the solute dissociates to form free ions, the electrolyte is strong; if most of the solute does not dissociate, the electrolyte is weak.
