WebThese solutes tend to be soluble salts and completely dissociate 100% to yield a solution of cations and anions. The actual concentration of ions will be the the mixed concentration times the number of ions in the formula. That number is the van’t Hoff factor. It is ideally equal to an integer number that is typically 2, 3, 4, or 5. WebThus, in extremely dilute solutions, the effective concentrations of the ions (their activities) are essentially equal to the actual concentrations.
