What Is the Ionic Strength of a Solution

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.

How do you find the ionic strength of a solution?

Multiply the squared charge numbers by the ionic concentration. Add up all the products of the ionic concentration and charge numbers. Divide the sum value by 2. The result is the ionic strength of the solution as mol/kg of solute or mol/L of solution.

How do you determine the strength of a solution?

Strength of solution = Mass of solute in grams/Volume of a solution in litres.
