Ostwald's Dilution Law
This law deals with the application of the law of mass action to the equilibrium between the ions and unionized molecules in aqueous solutions of weak binary electrolytes such as acetic acid, propionic acid, `HCN, NH_4OH`, etc.
Consider a dilute solution of a weak binary electrolyte `AB` containing `c` moles in `1` litre.
At any given temperature, there will be equilibrium between the unionized molecules of `AB` and the ions `A^+` and `B^-` . let `'alpha'` be the degree of dissociation of `AB` at equilibrium.
`AB ⇋ A^(+)+B^(-)`
