Ionic Strength Calculator
Top
The quantity used to characterize aqueous solutions that contain different concentrations of ions is the ionic strength. The ionic strength is a measure of the magnitude ionic strength and increase as the concentration of ions increases.

The Ionic Strength Calculator calculates half of the total sum of the concentration of every ionic species.

  1. Calculate the ionic strength of a 1 M KCl and 1 M CaCl2 solution.


    Step 1 :  

    Form a table with the given values :

    IonsZCZ2
    K+111
    Ca2+214
    Cl-131


    Step 2 :  

    I = $\frac{1}{2}$ [ (1$\times$1) + (4$\times$1) + (1$\times$3)]

    I = 4



    Answer  :  

    The ionic strength of the given solution is 0.4



  2. Calculate the ionic strength of an H3PO4 molar solution.


    Step 1 :  

    Form a table with the given value.

    Ions

    ZCZ2
    H+131
    PO43-319


    Step 2 :  

    I = $\frac{1}{2}$ [3 $\times$ 1 + 1 $\times$ 9 ]

    I = 6



    Answer  :  

    The ionic strength of the given solution is 6.
